Abstract
The present invention teaches a method for enabling the formation of a high damping compound. The method includes: reacting a poly(disubstituted ethylene-co-maleic acid anhydride) polymer with a primary amine under substantially dry conditions sufficient to form a poly(disubstituted ethylene-co-maleimide) polymer plasticizer; and, dispersing the poly(disubstituted ethylene-co-maleimide) polymer plasticizer within a rubber formulation to form a relatively high damping compound.
Claims6
A plasticizer for an elastomer comprising:
- a poly(R1 (R2)ethylene-co-maleimide) copolymer wherein R1 and R2 are the same or different substituents selected from the group consisting of unsubstituted and substituted C1 to C20 alkyl groups.
