Abstract
Ethyl 2-[1-((2-tetrahydrofuranyl)peroxy)ethyl]propenoate (ETPEP) was used as a new chain transfer agent in the free radical polymerization of methyl methacrylate (MMA), styrene (St), and butyl acrylate (BA) to produce α,ω-difunctional telomers through a radical addition-substitution-fragmentation transfer reaction. The chain transfer constant obtained in the MMA polymerization at 60°C (C tr = 0.096) was very low compared to those obtained in styrene and butyl acrylate under the same conditions (C tr =0.97 and 1.02, respectively). Such a result was attributed to the bulkiness of the α-substituents of both monomer and transfer agent in the addition step of the transfer reaction
