Abstract
Copolymerization of styrene-terminated poly(ethylene oxide) (PEO) macromonomer (SEOM) and styrene (St) with Ni(acac)2/MAO catalyst was investigated. The copolymerization of SEOM and St with the Ni(acac)2/MAO catalyst proceeded to give a high molecular weight graft copolymer consisting of hydrophobic styrene units as the main chain and hydrophilic PEO units as the side chains. The numbers of graft chains were controlled by varying SEOM contents in the comonomer feed. The graft copolymer obtained from the copolymerization of SEOM and St with Ni(acac)2/MAO catalyst contained isotactic triad in a lower amount than that of poly(St) obtained with Ni(acac)2/MAO catalyst.
