Centipede polymers grafted with hydrogenated block copolymers and polypropylene and gels thereof
First Claim
1. A method for the formation of a graft copolymer, comprising:
- reacting from about 10 wt % to about 50 wt % of a poly(alkenyl benzene-co-maleimide) and about 90 wt % to about 50 wt % of a mixture of a maleated polyalkylene and a maleated hydrogenated block copolymer in a weight ratio of from 10;
1 to 1;
10, and from about 0.1 to about 10 wt % of a diamine under substantially dry conditions sufficient to form a hydrogenated block copolymer-polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer.

Abstract
The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(alkenyl benzene-co-maleimide) polymer with a maleated polyalkylene and a maleated hydrogenated block copolymer and an alkyl diamine grafting agent under substantially dry conditions sufficient to form a hydrogenated block copolymer-polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product; and, dispersing the hydrogenated block copolymer-polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product with an extender oil sufficient to form the gel. The present invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.
