Among the various synthetic rubbers used in the rubber industry, one elastomer isAlkyl Acrylatesas the base material and withA small amount of monomers with cross-linking active groupsThe copolymer produced by copolymerization, its main chain is saturated and contains polar ester groups, scientists named it asAcrylate rubber［ACM］。

     Although the proportion of synthetic rubber currently used is not large, with the rapid development of the automobile industry, itsOil and heat resistantThe comprehensive performance is suitable for the rubber parts contacting various parts of the hot oil engine.

     In fact, the development history of acrylic rubber is no later than that of other synthetic rubbers, and it has been a hundred years since the beginning of time.。In the 1960s, when our country had not yet made a deep understanding of it, the American company Cyanamide had already begun industrial production and put it on the market for the manufacture of rubber parts that contact hot oil. After that, Japan, Germany, Canada, and the former Soviet Union produced ACMs one after another, and thanks to the development of high-speed cars in the 1960s, the demand and development of ACMs played a big role in promoting them.

   There are many commercially available varieties of acrylic rubber and brands produced by various manufacturers, and the classification methods are also inconsistent.monomerclassification, can be divided into：

［1］Ethyl Acrylate/Oxyethyl Ethyleneether

［2］Ethyl Acrylate/Acrylonitrile

［3］Butyl Acrylate/Acrylonitrile
