摘要：【中文】本发明公开了一类新型硫化剂及其在聚合物中的应用，该硫化剂在聚合物加工时加入，可在聚合物中形成交联网络，提高材料力学性能；同时该交联剂在高温时又可使聚合物材料解交联，其降温后可再次交联产生网络结构，赋予聚合物材料反复加工的热塑性。本发明的硫化剂可解决高分子材料交联增强和回收利用的矛盾。 【EN】The invention discloses a novel vulcanizing agent and application thereof in polymers, wherein the vulcanizing agent is added during the processing of the polymers, so that a cross-linked network can be formed in the polymers, and the mechanical property of the materials is improved; meanwhile, the cross-linking agent can enable the polymer material to be de-cross-linked at high temperature, and can be cross-linked again to generate a network structure after being cooled, so that the polymer material is endowed with thermoplasticity through repeated processing. The vulcanizing agent of the invention can solve the contradiction between crosslinking enhancement and recycling of high polymer materials.
