Abstract
The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(alkyl vinylether-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(alkyl vinylether-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(alkyl vinylether-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.

A method for the formation of a high damping centipede polymer, comprising:
- reacting from about 50 wt % to about 99 wt % of a poly(alkyl vinylether-co-maleimide) wherein the alkyl group of the alkyl vinylether contributed monomer units is selected from the group consisting of unsubstituted and substituted C1 to C20 alkyl groups, and about 1 wt % to about 50 wt % of a maleated polyalkylene and from about 0.1 to about 10 wt % of a diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(alkyl vinylether-co-maleimide) centipede polymer.
A high damping centipede polymer gel composition, comprising:
- a polyalkylene grafted poly(alkyl vinylether-co-maleimide) wherein the alkyl group of the alkyl vinylether contributed monomer units is selected from the group consisting of unsubstituted and substituted C1 to C20 alkyl groups comprising from about 50 wt % to about 90 wt % of a poly(alkyl vinylether-co-maleimide) and about 10 wt % to about 50 wt % of a maleated polyalkylene and from about 0.1 to about 10 wt % of a diamine, and an extender in an amount sufficient to from a gel.
A polyalkylene grafted poly(alkyl vinylether-co-maleimide) wherein the alkyl group of the alkyl vinylether contributed monomer units is selected from the group consisting of unsubstituted and substituted C1 to C20 alkyl groups comprising:
- from about 50 wt % to about 90 wt % of a poly(alkyl vinylether-co-maleimide) and about 10 wt % to about 50 wt % of a maleated polyalkylene and from about 0.1 to about 10 wt % of a diamine.
A centipede polymer, comprising:
- a polyalkylene grafted poly(alkyl vinylether-co-maleimide) wherein the alkyl group of the alkyl vinylether contributed monomer units is selected from the group consisting of unsubstituted and substituted C1 to C20 alkyl groups.
