ABSTRACT:
The present invention teaches a method for enabling the formation of a high damping compound. 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 within a rubber formulation to form a relatively high damping compound. The present invention also contemplates a rubber compound composition and an article manufactured from the composition.
