摘要：
1,2,3-Triphenylcyclopropene (TPCP) is a powerful retarder for polymerizations of methyl methacrylate (MMA) and styrene initiated by benzoyl peroxide or azobisisobutyronitrile. End-groups in polymers of MMA were studied by 13C-NMR spectroscopy and also, in the case of the peroxide, by using radioactive initiator. It was shown that, towards the benzoyloxy and 1-cyano-1-methylethyl radicals, the reactivity of TPCP exceeds that of MMA by factors of about 60 and three respectively at 60-degrees-C. TPCP can be used to introduce into polymers end-groups of special types.
