摘要
本本文采用丙烯酸羟乙酯与六氯环三磷腈反应合成三种化合物,丙烯酰氧乙氧基五甲氧基环三磷腈,二丙烯酰氧乙氧基四甲氧基环三磷腈和三丙烯酰氧乙氧基三甲氧基环三磷腈单体。并用红外对单体结构进行了表征。然后利用α-二亚胺Pd催化剂通过链行走催化乙烯与合成的三种化合物共聚,制备了具有交联结构的新型超支化聚合物。对聚合物的交联度进行了比较。并用红外对聚合物结构进行了表征。
AOne hydroxyethyl aerylate substituted hexachlorocyclo triphosphazene compound(Compound A),two hydroxyethyl acrylate substituted hexachlorocyelo triphosphazene compound(Compound B),three hydroxyethyl acrylate substituted hexachlorocyclo triphosphazene compound(CompoundC) were successfully synthesized with hydroxyethyl acrylate and hexachlorocyclo triphosphazene.Then,the novel cross-linking hyperbranched polyolcfins prepared from copolymerization of ethylene with Compound A,Compound B and Compound C via chain walking polymerization using(?)-diimine Pd as catalyst ,the IR results showed that cross-linking hyperbranched polyolefins have successfully produced.
