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