    摘要: A thermoplastic elastomer composition has a plastic phase or matrix of an engineering thermoplastic such as a polyamide and a crosslinked phase of cured acrylic rubbers. The rubbers contain at least two functionalized acrylic rubbers wherein the functional group such as a carboxyl, an epoxy, or a hydroxyl can be the same or different. The curing agents generally react via covalent bonding with the reactive functional groups of the rubbers. The composition can be dynamically vulcanized and when one of the rubbers is a terpolymer of ethylene-alkyl acrylate-unsaturated carboxylic acid, the composition has a single low temperature brittle point.

    摘要: Crosslinking of rubber having a carboxylic functionality is accomplished by heating the rubber in the presence of an isocyanate functionalized compound and an accelerator which is a metal salt of an organic acid. The crosslinked polymers are useful in a variety of shaped articles, and can be in the form of dispersed particles, in a continuous plastic phase.
