Title:
【発明の名称】塩素化ポリエチレンと結晶質オレフィンポリマーとに基づく熱可塑性エラストマー材料の製造方法
Document Type and Number:
Japanese Patent JP3015037
Kind Code:
B2
Abstract:
Thermoplastic vulcanizates are prepared by curing, at least partially by dynamic vulcanization, blends of chlorinated polyethylene and crystalline thermoplastic polymers especially polyethylene or polypropylene. Inclusion of a plasticizing material or extender oil, e.g. trioctyl trimellitate, enhances softness and oil resistance of the blends. Vulcanizing materials include a basic material, normally added with the chlorinated polyethylene, and a derivative of 2,5-dimercapto-1,3,4-thiadiazole or a combination of 2,5-dimercapto-1,3,4-thiadiazole and an activator material such as an amine having a boiling point of 110 DEG C or higher and a pK value less than 4.5.
