there was evident reduction in the increasing speed of synthetic rubber production among 1980s except EPDM

TPE and carboxylated latex. Most producers put emphasis on improvement of characteristic and using performance of original rubber products and devoted to develop more and more new elastomers with various modification technologies. In this article

there has a brief description on the improvement route of quality of synthetic rubber. Besides

it also summarized the basical feature of thermoplastic elastomers and various chemical and physical modification technologies for superior performance. Finally there has prospects on the R&D of elastomers for the 1990s.
