Abstract First I must thank you Mr. Chairman for your most generous introduction. I understand that there will be another opportunity later today to thank the Executive Committee of the Rubber Division of the American Chemical Society for nominating me as the Charles Goodyear Medalist for 1986, for the pleasure of being here today, and for the privilege of addressing you. But I would wish to say, at this stage, how deeply honored I am to receive this most distinguished award. It is a tradition that this address should reflect the author's special interests and his own contribution to rubber science and technology, and they have tended to be autobiographical in nature. However the title which I have chosen, “Engineering with Rubber,” covers a broad field of activity, but in the relatively short time at my disposal I will perforce have to restrict myself to those areas in which I have been personally involved. Like so many recent Charles Goodyear Medalists it was my good fortune to be active during the period of almost explosive growth of polymer science and technology which occurred during the 1940's and 1950's and which provided a proper scientific basis for the polymer industries created during this period. The rubber industry is, of course, much older, but hitherto it had relied upon an essentially empirical approach to provide practical answers to most of its problems. It was also my good fortune to work with and alongside many outstanding individuals both at the Research Association of British Rubber Manufacturers (now the Rubber and Plastics Research Association) and at the Malaysian Rubber Producers' Research Association (formerly the British Rubber Producers' Research Association). To these I owe much and I would wish to share this recognition with my colleagues.

Abstract I am greatly honored to have been selected to receive the prestigious Charles Goodyear Medal of the Rubber Division of the American Chemical Society. My work in the rubber field falls into two general areas: (1) early discoveries on the redox emulsion polymerization of styrene-butadiene rubber (SBR) and (2) polyether elastomers. I am perhaps best known for my work on polyether elastomers since I discovered, patented, and helped develop several families of polyether elastomers which were commercialized and are still important speciality elastomers. Most of my talk will be in that area. However, my SBR studies included my first important polymer-science discovery and preceded those who independently discovered the same systems and who were able to develop them commercially to the considerable advantage of our largest volume synthetic rubber, SBR. After briefly reviewing these past areas, I will give you my reflections on what important future developments for the rubber field could arise in the polyether area.

Abstract THE effect of relative humidity on rubber-testing has been the subject of much recent investigation. String-field and Conover and Depew have published papers on this subject. The last-named authors recommended that the rubber be stored in dry cabinets before milling, between milling and vulcanization, and between vulcanization and testing, at a temperature of 75° ±5° F. A short time later the Physical Testing Committee of the Rubber Division of the American Chemical Society recommended that all laboratory testing be carried out at 45 per cent relative humidity and 82° ±5°F. While both methods have undoubted merit, it was believed that for physical testing laboratories, particularly such as this one, zero humidity was both more conducive to reliable results and easier to maintain. Accordingly, equipment was installed for maintaining zero humidity and its performance has been consistently good. Since several of the larger rubber laboratories have shown interest in the equipment, it has been decided to present this description of the installation and its operation.
