摘要:
Thermoplastic elastomers containing ethylene, alpha-olefin, vinyl norbornene elastomeric polymers provide superior cure levels to thermoplastic elastomers containing ethylene, alpha-olefin, diene monomer elastomeric polymers with other dienes than vinyl norbornene. The elastomeric polymers, along with a thermoplastic, curative, and other components will have cure levels in excess of 95 percent. Lower diene incorporation into the polymer combined with lower curative levels yield a fabricated article with improved resistance to compression set and improved heat aging.
