US 2001/0034393 A1 · Gels derived from extending grafted centipede polymers and polypropylene

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 an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product; and, dispersing the 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.

A method for the formation of a high damping centipede polymer, comprising:

reacting from about 50 wt % to about 99 wt % of a poly(alkenyl benzene-co-maleimide) 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(alkenyl benzene-co-maleimide) centipede polymer.

A centipede polymer composition, comprising:

a polyalkylene grafted poly(alkenyl benzene-co-maleimide) comprising from about 50 wt % to about 99 wt % of a poly(alkenyl benzene-co-maleimide) and about 1 wt % to about 50 wt % of a maleated polyalkylene and from about 0.1 to about 10 wt % of a diamine.
