EPDM是一种由乙烯-丙烯、二烯单聚物构成的三元共聚物弹性材料。

EPDM is a terpolymer elastomer made from ethylene-propylene diene monomer.

三中单体的聚合产生了具有两相的三元共聚物，一个是苯乙烯-丙烯腈的连续相， 另一个是聚丁二烯橡胶分散相。

The polymerization of the three monomers produces a terpolymer which has two phases: a continuous phase of styrene-acrylonitrile (SAN) and a dispersed phase of polybutadiene rubber.
