ABSTRACT:
The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting in a suitable solvent a poly(alkenyl benzene-co-maleic anhydride) and a primary amine to form a poly(alkenyl benzene-co-maleimide) polymer. The poly(alkenyl benzene-co-maleimide) polymer while remaining in solvent is grafted with a maleated polyalkylene through the use of a grafting agent such as an alkyl diamine to form a polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product. The solvent is then removed from the polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product and the polymer is mixed with extender such as oil sufficient to form the gel. During oil extension the graft copolymer is further crosslinked due to the presence of additional alkyl diamine.
