The GPC/SEC system with RI, VIS and LS was adopted for determination of the absolute molecular weight and its distribution of EVA, and the test conditions involved were optimized. The results showed that EVA's absolute molecular weight and its distribution, intrinsic viscosity, Mark-Houwink coefficient and molecular size could be detected accurately by this method.
