Title:
THERMOPLASTIC ELASTOMERS HAVING IMPROVED SET AND FOAMS MADE THEREFROM
Document Type and Number:
WIPO Patent Application WO2002059194
Kind Code:
A3
Abstract:
A thermoplastic vulcanizate prepared by a process comprising the steps of dynamically vulcanizing a vulcanizable rubber within a mixture that includes from about 15 to 90 percent by weight of the rubber and from about 10 to about 85 percent by weight of a long-chain branched thermoplastic resin, where the long-chain branched thermoplastic resin is: i) an alpha -olefin polymer; ii) a copolymer of an alpha -olefin and an alpha - omega -olefin diene; or iii) a mixture thereof, where the long-chain branched thermoplastic resin is characterized by a weight average molecular weight from about 100, 000 to about 600,000, a number average molecular weight from about 40,000 to about 200,000, a z-average molecular weight from about 400,000 to about 2,000,000,avis from about 0.2 to about 0.95, and a melt flow rate from about 0.3 to about 30dg/min.
