Abstract
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.
Claims18
A method for the formation of a high damping polymer, comprising:
- reacting from about 20 wt % to about 99 wt % of a poly(alkenyl benzene-co-maleimide) having minor or trace amounts of maleic anhydride contributed monomer units and about 1 wt % to about 80 wt % of a nylon under substantially dry conditions sufficient to form a nylon grafted poly(alkenyl benzene-co-maleimide) polymer, and mixing the nylon grafted poly(alkenyl benzene-co-maleimide) polymer with an extender in an amount sufficient to form a gel.
A polymer gel composition, comprising:
- a nylon grafted poly(alkenyl benzene-co-maleimide) comprising from about 20 wt % to about 99 wt % of a poly(alkenyl benzene-co-maleimide) having minor or trace amounts of maleic anhydride contributed monomer units and about 1 wt % to about 80 wt % of a nylon, and an extender in an amount sufficient to form a gel.
