摘要：
Raw polymer and compound of hydrogenated acrylonitrile butadiene rubber (HNBR) were subjected to gamma-ray irradiation. Crosslinking was found to be the main chemical reaction induced by irradiation; the ratio of chain scission to crosslinking as well as the dose at which gelation occurred were determined from gel content measurements to be 0.41 and 3.8 Mrad, respectively. The excellent hot-air and oil-resistant properties should be retained because no formation of double bonds or changing of the nitrile groups were observed within the optimum dose range. Desired mechanical properties of the vulcanizate may be conveniently obtained by controlling the radiation dose. (C) 1994 John Wiley & Sons, Inc.
