The anionic dispersion polymerization of α‐methylstyrene

摘要

AbstractA new technique for the anionic polymerization of α‐methylstyrene has been developed. By using an aliphatic hydrocarbon as the diluent, hexamethylphosphoramide as promoter, and a poly(vinyl alkyl ether) as interfacial agent, the high molecular weight polymer is obtained as a uniform dispersion. The advantages of the method are high conversions at low viscosities and an economical isolation procedu
