We wish to thank Dr. A.F. Halasa of Goodyear Tire and Rubber Company (Akron, Ohio) for supplying the polybutadiene material which made this work possible. 

The materials selected for evaluation included three materials currently being used in these applications Biomer (Thoratec Laboratories Corporation, Emeryville, CA), representative of segmented ether-type polyurethanes Avcothane-51 (Avco Everett Research Laboratory, Inc., Everett, MA), a block copolymer of 10% silicone rubber and 90% polyurethane and Hexsyn (Goodyear Tire and Rubber Company, Akron, OH), a sulfur vulcanized hydrocarbon rubber that is essentially a polyhexene. Also selected, because of their easy availability, were Pellethane (Upjohn Company, North Haven, CT), an ether-type of polyurethane capable of being extruded in sheet form, and a butyl rubber formulation, compounded and molded at the National Bureau of Standards. The material thickness varied, but the sheets were generally about 1 mm thick.

A number of the giant tire companies started at the turn of the century. In America many of these companies centered around Akron, the capital of the rubber tire. In 1898 the Goodyear Tire and Rubber Company started. The Firestone Tire and Rubber Company was started by Harvey Firestone in 1900. Other tire companies shortly followed.

Goodyear invented a material that would eventually be used in thousands of ways and opened the door for a huge industry. Today there is one rubber tree for every two people on Earth. Despite this, he died destitute in New York on July 1, 1860. Although the Goodyear Tire and Rubber Company was named in his honor, Goodyear s descendants had little to do with the rubber industry after his death, see also Polymers, Natural Rubber.

Materials. The starting PP was kindly provided by the Goodyear Tire and Rubber Company. It contains 82% trans and 17% cis double bonds with fewer than 1% vinyl side groups. The molecular weight averages are Mw = 172,000 and = 470,000. The PP was sulfonated using a 1 1 complex of sulfur trioxide with triethyl phosphate in chloroform at room temperature. The sulfonated material was neutralized by precipitating the reaction mixture into a 0.25M solution of NaOH in ethanol. This reaction is described in detail elsewhere (5) and is summarized as follows ...
