Cosy Corners in Depression and War
1979 In September 1978 I had been engaged for a feasibility study entitled "The Influence of salts of organic acids on the crystallinity of partly hydrolysed polyvinylacetate polymers." I wrote a report which presented our case very well and Dr. Pritchard submitted an application for a grant for further work to the appropriate authorities. Most of the work was finished by March 1979 and I employed the following two months to write the report, doing most of the work at home. Though when I started I had not much enthusiasm for this project, I found some of the work to be interesting and soon became engrossed with it. I was using gel filtration chromatography to prepare samples of polyvinylacetate free from sodium and potassium ions. This was a method described in Skoog and West, a book written for analytical chemists by colleagues of Professor Belcher from my old department at Birmingham University. It is more difficult to use chromatography to prepare quantities of pure chemicals than to use it for analysis of samples. We soon found that it was better to shake the impure sample with the gel in suspension and leave it stand in a flask overnight. In this way we prepared our samples in amounts up to 2.5 grams. This was sufficient to form a thin film suitable to examine by means of a geological microscope. We were looking to see if light was scattered by the samples differently in different planes. This resulted in colours being shown which could be photographed. I have some interesting photographs in my report. Impure PVA products containing sodium or potassium acetate show birefringence. Polarised light of a fixed band of wavelengths travels through the solid more slowly in one direction than in another, producing varying colour effects. This indicates that the molecules in the polymer are oriented in a preferred direction. The work can best be described by giving the objectives of the study and the conclusion reached, as follows: Objective of the study 1. To investigate and understand crystallinity in partly hydrolysed polyvinyl acetate polymers. 2. To determine whether crystallinity can be observed in partly hydrolysed polyvinyl acetate polymers independently of the presence of salts of organic acids present as impurities or deliberately introduced. Summary of report and conclusions A review of the physical aspects of polymer crystallinity is given. Partly hydrolysed polyvinyl acetate polymers with 90 mole-% of hydroxyl units have been prepared, analyzed chemically and examined with a polarising microscope. A method has been devised for separating salt from the polymers. It has been demonstrated that these polymers exhibit their partial crystallinity independently of the presence of up to 7% of sodium or potassium acetate. The presence of up to 7% of acetate salts has been demonstrated to enhance the film forming properties of the polymers by the prevention of bubble formation. Hydrolysed polyvinyl acetate polymers which are partly crystalline and compatible with organic salts may be useful commercially in the form of transparent films with special optical properties (which might be used, for example, in eye lenses). This report looks very dry to non-technical readers, but the practical work on the bench was my favourite kind of work and what I was always happiest doing. By May 1979 the report was complete and Dr. Pritchard had applied for funding for further work on this project. Unfortunately his application was turned down. I was heartbroken in June 1979 as I was told the chemistry department was going to be scaled down and no new projects started. Meanwhile Joy had just completed her work on lead in hair from dentists and had been engaged by London Hospital as a medical technician. She had had experience in this field before marriage. I knew there was no chance for me in this field. As I had failed to gain employment in chemistry after my last period at North East London Polytechnic, I doubted whether I would be successful now. I was feeling very tired. Just before going home from the Polytechnic for the last time Joy took me out to lunch at the Co-operative Store in Stratford. At this time they had two eateries, a self-service cafe on the ground floor and a restaurant with waitress service on the first floor. On this occasion we went to the restaurant and had a delicious curry. I said good-bye to Joy and doubted that I would keep in touch. I was short of money and would have to sign on unemployed until I found a job. I sent away a few applications for work in laboratories, but I was now 51 years of age and my CV did not look very good. There were too many gaps. Even though I had done successful laboratory work at the polytechnic it looked very unlikely that I would find employment in chemistry. I was very disappointed, but did not regret working at the polytechnic even though it did not lead to further work. I became resigned to the idea of working in an office again. There were still a few such jobs available. Mrs. Margaret Thatcher had just won the General Election. Unemployment stood at just over a million. Unfortunately Mrs. Thatcher was proceeding to cut funds from many educational establishments which might have employed me. When Charles Hill, a friend of Andrew's visited 177 Glenarm Road and told me that he was working at Central Books and a job in the office had just become vacant, he asked me to apply for it and said he would give me a recommendation. There did not seem to be any other work in view so I took this chance.
Four applicants were interviewed. Andrew's daughter, Lily answered the phone when Dave Wynn, Manger of Central Books called. Lily was about 12 years of age, and I wondered whether this would give him a favourable impression or otherwise. I don't think it mattered. I was the one who got this job. I started this work about September 1979. When I arrived in the office, a young woman of about 20 started to teach me the job. She was leaving in three weeks time to start university. I believe she intended to take a degree in English as in her spare time she was reading "Ulysses" by James Joyce. I found this book too difficult to read when I tried it. I've forgotten her name so shall call her Ann. Ann had very red, dyed hair. I believe this was a "punk" style. Her sister, Brandy, worked part-time. She was about five years older than Ann and a married woman. Ann was surprised at how quickly I learned the work, which was concerned with the export of books in English to Eastern Europe and China. There was a book of instructions prepared by Brandy and I found this very useful. At Central Books I was moderately happy during the first year. The pay was £60 per week, not high but my expenses were low, so I was able to save money.
