Abstract

The mapping of the termination rate coefficient as a function of the chain lengths of the terminating radicals using the reversible addition fragmentation chain transfer (RAFT) polymerization process was investigated. Methyl acrylate (MA) was freed from inhibitor by percolating over a column of activated basic alumina. Solutions of MS with AIBN and methyl propionate for the determination of the monomer reaction order or RAFT agent for the CLD-T measurements were thoroughly deoxygenated via for subsequent freeze-pump-thaw cycles. MA free radical polymerization displayed nonidealities due to the presence of less reactive midchain radicals.
