摘要 |
This invention relates to grafted ethylene-higher alpha-olefin polymers and blends thereof. Preferred grafted ethylene-higher alpha-olefin polymers are multimodal EPDM's having 5-40 weight % of a higher molecular weight, higher ethylene content, lower diene content fraction grafted with maleic anhydride. These polymers can then be used as modifiers for additional polymers such as polyamides, polyesters, and other EPDM's.
