通过工业聚氯乙烯颗粒吸收苯乙烯,二乙烯苯混合物或通过苯乙烯—二乙烯苯共聚物珠体吸收氯乙烯单体,合成了一系列互贯树脂.由后者途径合成的树脂与前者途径合成的树脂相比,具有更高的机械强度和较低的膨胀系数.互贯树脂的物理机械性质主要依赖于互贯树脂的第一次聚合物.当互贯树脂中的聚氯乙烯胺化时同时有其他副反应发生,适当调节温度可以控制聚氯乙烯胺化反应进行.带有两个以上胺反应性官能团的溶剂或多胺基的胺化剂皆能使树脂在胺化反应时提高交联度,因而也就促进了这些树脂的物理和化学稳定性的提高.
A series of interpenetrating resins were synthesized by absorbing vinyl chloride monomer from a mixture of styrene and divinylbenzene through industrial polyvinyl chloride particles or through styrene-divinylbenzene copolymer beads. The resin synthesized by the latter approach was similar to the former Compared with the synthesized resin, it has higher mechanical strength and lower coefficient of expansion.The physical and mechanical properties of the interpenetrating resin are mainly dependent on the first polymer of the interpenetrating resin.When the polyvinyl chloride in the interpenetrating resin is aminated While other side effects occur at the same time, the appropriate temperature control PVC amination reaction can be controlled with more than two amine-reactive functional groups of the solvent or polyamino amine agent can make the resin in the amination reaction The degree of crosslinking, therefore, also promotes the physical and chemical stability of these resins.
