    摘要: The instant invention relates to poly(maleimide-co-alkenyl benzene) centipede polymer and a method for producing the polymer by reacting a poly(alkenyl benzene-co-maleic anhydride) in the presence of a primary amine in a substantially dry state. The invention is further directed to a process for blending the poly(maleimide-co-alkenyl benzene) centipede polymer with elastomeric polymers, in combination with, or in substitution of, conventional extender oils, to produce extended polymers having improved properties such as tensile strength, maximum elongation, tear strength, damping properties, and the like.

    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.

    摘要: A process for forming a nanoparticle composition is provided. The process includes polymerizing conjugated diene monomer in a hydrocarbon solvent to form a first reaction mixture, and charging excess alkenylbenzense monomer and anionic catalyst to form mono-block and diblock polymers. Micelles of said mono-block and diblock polymers are formed, and at least one crosslinking agent is added to cross-link the micelles and form nanoparticles. The nanoparticles preferably have a poly(alkenylbenzene) core and an outer layer including monomer units selected from the group consisting of conjugated dienes, alkenylbenzenes, alkylenes, and mixtures thereof, and a size distribution of between about 1 and 1000 nm.
