Abstract

The chain transfer to monomer constants (CM) in homopolymerization of 2-methylene-1,3-dioxepane and its copolymerization with styrene are determined under different conditions using the chain length distribution analytical method. The obtained chain transfer constant value CM = (1.2-1.6) × 10−2 is 2-3 orders of magnitude higher than that for polymerization of vinyl monomers such as styrene, MMA and others. Therefore, the chain transfer to monomer is the main chain-growth termination reaction in radical ring-opening polymerization of ketene acetals.
