Abstract

Radical control: Controlled free-radical polymerization of styrene and methyl (meth)acrylate is achieved by using Davy reagents or P4S10 in conjunction with benzoic acid, which leads to in situ formation of dithioesters that act as chain-transfer agents and thus control the reaction. In the case of P4S10/PhCOOH, d[thiobenzoic acid is the key intermediate in this process (see scheme).
