Controlled radical polymerization of acrylates by γ -irradiation in the presence of 1,1-diphenylethene

Poly (butyl acrylate) and poly (methyl acrylate) were successfully prepared in the presence of 1,1-diphenylethene (DPE) by γ -irradiation-induced polymerization in both bulk and solution. The influences of polymerization time, amounts of DPE in system on conversion, molecular weight (MW) and its dis...

Zusammenfassung:	Poly (butyl acrylate) and poly (methyl acrylate) were successfully prepared in the presence of 1,1-diphenylethene (DPE) by γ -irradiation-induced polymerization in both bulk and solution. The influences of polymerization time, amounts of DPE in system on conversion, molecular weight (MW) and its distribution ( M w/ M n) were studied. The results indicate that the polymerization initiated by γ -irradiation in the presence of DPE shows the character of living radical reaction.
