摘要:
The instant invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(maleimide-co-alkenyl benzene) polymer with a nylon and an alkyl diamine under substantially dry conditions sufficient to form a nylon grafted poly(maleimide-co-alkenyl benzene) polymer product; and, dispersing the nylon grafted poly(maleimide-co-alkenyl benzene) polymer product with an extender oil sufficient to form the gel. The instant invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.

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