ETHYLENE-ALPHA OLEFIN-DIENE RESIN BLEND COMPOSITION AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to an EPDM resin blend composition, which includes a first EPDM resin matrix and a second EPDM resin, wherein a ratio (M w1 /M w2 ) of a weight average molecular weight of the first EPDM resin matrix to a weight average molecular weight of the second EPDM resin ranges from 0.75 to 1.33, and the second EPDM resin has a narrower molecular weight distribution (M w /M n ) than the first EPDM resin matrix, and to a method for preparing the same.
