Abstract
A process for producing a thermoplastic elastomer composition, the process comprising synthesizing an elastomeric copolymer by polymerizing ethylene, an α-olefin, and optionally a diene monomer within the gas phase to thereby produce a gas-phase elastomeric copolymer, blending the gas-phase elastomeric copolymer with a thermoplastic polymer to form a mix of the elastomeric copolymer and thermoplastic polymer, and dynamically vulcanizing the gas-phase elastomeric copolymer within the mix of the elastomeric copolymer and thermoplastic polymer.
