There are two forms of liquid latex and fixed rubber. Styrene odor, not completely soluble in gasoline, benzene and chloroform.
latex was prepared by emulsion copolymerization of butadiene and styrene with rosin acid soap or fatty acid soap as emulsifier and persulfate as initiator, and then coagulated and dried to obtain solid rubber. The 75/25 solid rubber can also be prepared by solution copolymerization of butadiene and benzene Diene in hexane with butyl lithium as catalyst.
