Abstract

Summary: Experimental and modeling studies of addition–fragmentation chain transfer (AFCT) during radical polymerization of methyl methacrylate in the presence of poly(methyl methacrylate) macromonomer with 2‐carbomethoxy‐2‐propenyl ω‐ends (PMMA‐CO~2~Me) at 60 °C are reported. The results revealed that AFCT involving PMMA‐CO~2~Me formed in situ during methyl methacrylate polymerization has a negligible effect on the molecular weight distribution.

The mechanism of catalytic chain transfer with bis(boron difluorodimethylglyoximate) cobaltate(I1) (COBF) has been studied in the homopolymerisations of methyl methacrylate and styrene. The chain transfer constants were measured using both the Mayo and Chain Length Distribution (CLD) methods over a
