The reactivitles of the E isomers of ~-methylstilbene (l,2-diphenylpropene) and ~@ -dimethylstilbene (2,3-diphenylbut-2-ene) towards the benzoyloxy radical have been compared by procedures involving the analyses of the end-groups in polymers of methyl methacrylate, prepared using benzoyl peroxide as
Benzoyl peroxide, doubly labelled with carbon-14 and tritium, has been used at 60 Β° to initiate polymerizations of methyl methacrylate (I) containing in turn the E,E-isomers of the following compounds:-l,l,4,4-tetraphenylbuta-l,3-diene (II), 1,2,3,4-tetraphenylbuta-l,3-diene (III) and 1,3-distyrylbe
l\*C-benzoyl peroxide has been used at 60 Β° to initiate polymerizations of vinyl formate, propionate, butyrate, benzoate and phenyl acetate at various concentrations in benzene. The relative numbers of benzoyloxy and phenyl end-groups in the various polymers have been determined; these numbers have
