The combination of CMRP with nitroxide-mediated polymerization (NMP),provides access to novel ABC triblock copolymers based on a nonconjugated monomer (vinyl acetate) and conjugated ones (such as acrylonitrile, styrene, n-butyl acrylate, or 4-vinylpyridine) has been reported. NMP is a very attractive controlled radical polymerization technique that allows the preparation of very well-defined polymers by using a combination of a nitroxide and a free-radical initiator or by employing alkoxyamines as both initiators and controlling agents. The first block, PVAc-Co (acac)2, was prepared by CMRP using Co(acac)2 as the controlling agent and V70 as the initiator at 30 °C in the bulk. Novel well-defined ABC triblock copolymers were thus produced by combination of CMRP and NMP techniques.
