    摘要: The present invention relates to the use of polymers near their gelation point as additives to hydrogenated block copolymers to form thermoreversible gels. More particularly, the compositions of this invention are elastomeric and exhibit improved damping capabilities over a wide temperature range and frequency range due to the addition of a novel near-gelation polymer damping additive.

    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(disubstituted ethylene-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(disubstituted ethylene-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(disubstituted ethylene-co-maleimide) 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.
