    • Dynamically partially cured composition comprising a peroxide-curable olefin copolymer rubber (such as EDPM) and a peroxide-decomposing olefin plastic (such as PE and PP) is improved by effecting the dynamic heat-treatment with addition of a peroxide-non-curable hydrocarbon rubber (such as PIB) and/or a mineral oil softener (process oil). The dynamic heat-treatment is preferably carried out not only in the presence of an organic peroxide but also in the presence of divinyl benzene. The elastomeric composition is thermoplastic and, with or without further blending with an olefin plastic, is processable by techniques conventionally used for thermoplastic resins. This elastomer composition and blends of the elastomer composition and olefin plastic can be used for producing foamed product in combination with decomposition type foaming agent (such as azodicarbonamide).
    • 包含过氧化物可固化的烯烃共聚物橡胶(如EDPM)和过氧化物分解烯烃塑料(如PE和PP)的动态部分固化的组合物通过加入过氧化物非固化烃进行动态热处理得到改善 橡胶(如PIB)和/或矿物油软化剂(加工油)。 动态热处理不仅在有机过氧化物的存在下而且在二乙烯基苯的存在下进行。 弹性体组合物是热塑性的,并且与或不进一步与烯烃塑料共混,可通过常规用于热塑性树脂的技术进行加工。 弹性体组合物和弹性体组合物和烯烃塑料的共混物可用于与分解型发泡剂(如偶氮二酰胺)组合生产发泡产品。
