摘要：

Studies have been made of the reactivities of 1,4-diphenyl-1,3-butadiene and 2,3-diphenyl-1,3-butadiene towards the benzoyloxy, p-fluorobenzoyloxy and 1-cyano-1-methylethyl radicals. The 1,4-isomer has very high reactivity towards the aroyloxy radicals but very low reactivity towards the substituted alkyl radical. The 2,3-isomer is moderately reactive towards all three initiating radicals. The results have been obtained by analyses for end-groups in samples of poly(methyl methacrylate) produced in the presence of one of the dienes with the appropriate source of initiating radicals. © 1990.
