【摘要】 <正> 带受阻胺基团的聚合物是一类新型光稳定剂,这类聚合物的合成研究已有一些报道,但是关于单体分子中的亚胺基对自由基聚合影响报道各不相同。 本文用偶氮二异丁腈(AIBN)为引发剂,对4-甲基丙烯酸-2,2,6,6-四甲基哌啶醇酯(MTMP)的均聚及其与苯乙烯(St)的共聚合进行了研究,同时也考察了MTMP的母体化合物4-羟基-2,2,6,6-四甲基哌啶(TMP)对St及甲基丙烯酸甲酯(MMA)聚合的影响,并对St-MTMP共聚合体系中介质的影响进行了初步探讨。更多还原

【Abstract】 The homopolymerization of MTMP and the copodymerization of this monomer with styrene were investigated. Homopolymerizations of styrene and methyl meth-acrylate were performed separately in the presence of model compound, 4-hydroxy-2,2,6,6-tetramethyl piperidine, under identical conditions. In the above polymerization with AIBN as initiator, the inhibition effect of compounds bearing piperidinyl imino group, is not obvious. The influence of solvents on the copolymerization of MTMP with styrene was discussed.更多还原
