摘要： In a first embodiment of the present invention, poisoning or deactivation of conventional homogeneous catalysts to be used in hydrogenation of the backbone unsaturation in liquid monofunctional and difunctional-terminated conjugated diene polymers, is prevented by reacting a blocking agent compound with the functional end groups present in these polymers. More specifically, subsequent to formation of a selected starting material monofunctional or difunctional-terminated conjugated diene polymer, a suitable blocking agent is reacted with the functional end groups of the polymer enabling relatively inexpensive titanium, iron, cobalt, or nickel-based homogeneous catalysts to be used in hydrogenating the backbone unsaturation of the polymer to a high degree. Subsequent to hydrogenation, the polymer is subjected to conventional hydrolysis using a mineral acid or base to remove the blocking groups and return the hydrogenated conjugated diene polymer to its original functionality. In a second embodiment, conventional homogeneous catalysts based on cobalt, nickel, titanium, or iron are utilized to hydrogenate low molecular weight liquid copolymers and homopolymers to a high degree. More particularly, butadiene-alkenylpyridine and butadiene-acrylate liquid copolymers and butadiene homopolymers are formed in a conventional manner are hydrogenated using such catalysts.

摘要： Thermooxidatively and hydrolytically stable perfluoroalkylene ether bibenzoxazole polymers containing hydrocarbon cure sites are synthesized by the polycondensation of a fluorocarbon bis(o-aminophenol) containing a hydrocarbon moiety and a perfluoroalkylene ether diimidate or dithioimidate ester. The polymers are readily curable to elastomers that are resistant to hydrolysis over a wide use-temperature range. Thus, the polymers are especially suitable for use in aerospace applications where extreme environments are encountered. In particular, the polymers are useful as seals, sealants, and the like.

摘要： The compression set [(70° C., 22 hr), (100° C., 22 hr)] of TPVs can be improved by substituting, within their respective constituent plastic phase, all or portions of polyolefins having a high melting point, with polyolefins having lower melting point (Tm from between 115° C. to 140° C.). Exemplary polyolefins having melting points in this range include homopolyethylene, syndiotactic polypropylene, and isotactic poly(1-butene). Composition and methods of formulating thermoplastic vulcanizates to achieve an improved high temperature (between 70° C. 100° C.) compression set by selecting between suitable polyolefins on the basis of melting point temperature and substituting from 30% to 100% of high melting point polyolefins with low melting point polyolefins in the plastic phase are taught.

摘要： High-temperature oil-resistant elastomers are prepared from butadiene alkenylpyridine copolymers, butadiene-acrylate copolymers, and copolymers of butadiene with 1,3-dienes containing fluorine. The unsaturated olefinic backbone and pendant unsaturation derived from the hydrocarbon diene of each of the copolymers is hydrogenated to a high degree by a catalyst which improves the heat resistance of the copolymer without hydrogenation of the polar groups thereof which would lower the oil-resistance of the copolymer. A complexing agent for the hydrogenation catalyst prevents poisoning of the catalyst by the polar groups of the copolymers thereby enabling the catalyst to complex with unsaturated sites along the olefinic copolymer backbone to achieve high levels of hydrogenation thereof.
