摘要： A process is developed for recycling a polyolefin cross-linked substance having a cross-linkage, a polyolefin foamed substance free from a cross-linkage or a polyolefin foamed substance having a cross-linkage. The process includes the step of heating the polyolefin cross-linked substance together with a cross-linkage breaking agent, whereby breaking the cross-linkage to recycle the polyolefin cross-linked substance into a moldable thermoplastic resin. Further, the process includes the step of adding a foaming-agent-decomposition facilitating agent to the polyolefin foamed substance in the course of thermally melting the polyolefin foamed substance, whereby decomposing a residual foaming agent remaining in the polyolefin foamed substance. Furthermore, the process includes the step of adding a foaming-agent-decomposition facilitating agent to the polyolefin foamed substance in the course of heating the polyolefin foamed substance to break the cross-linkage, whereby decomposing a residual foaming agent remaining in the polyolefin foamed substance. The resulting recycled product is improved in terms of moldability, strength, elongation and superficial appearance.
摘要翻译：开发了一种用于回收具有交联键的聚烯烃交联物质，不含交联的聚烯烃发泡物质或具有交联键的聚烯烃发泡物质的方法。该方法包括与交联破坏剂一起加热聚烯烃交联物质的步骤，由此破坏交联以将聚烯烃交联物质再循环到可模制热塑性树脂中。此外，该方法包括在热熔聚烯烃发泡物质的过程中向聚烯烃发泡物质中加入发泡剂分解促进剂的步骤，从而分解留在聚烯烃发泡物质中的残余发泡剂。此外，该方法包括在加热聚烯烃发泡物质的过程中向聚烯烃发泡物质添加发泡剂分解促进剂以破坏交联的步骤，从而分解留在聚烯烃发泡物质中的残留发泡剂。所得到的再生产品在成型性，强度，伸长率和表面外观方面得到改善。

摘要： An oil resistant diaphragm having a liquid contacting surface made of a vulcanized rubber composition of, or composed mainly of, partially hydrogenated unsaturated nitrile-conjugated diene copolymer rubber in which at least 50% of the conjugated diene units is hydrogenated. This diaphragm is superior in resistance to deteriorated gasoline and low temperature, and is suitable for the automobile fuel pump.
