Cooperative reduction of various RAFT polymer terminals using hydrosilane and thiol via polarity reversal catalysis

Author affiliations

Abstract

Cooperative reduction of thiocarbonylthio terminals of polymers obtained by RAFT polymerization was investigated using a catalytic amount of thiol as a polarity reversal catalyst in conjunction with hydrosilane as a reducing agent. A combination of C12H25SH and Ph3SiH enabled the complete removal of xanthate, dithiobenzoate, and trithiocarbonate groups from poly(vinyl acetate), polystyrene, and poly(methyl acrylate) under the radical conditions.
