【摘要】 <正> 近十年来,对大分子单体的合成和表征进行了较广泛的研究,其中尤以聚苯乙烯大分子单体研究得更多。Milkovich等用阴离子聚合合成了一系列具有不同端基的大分子单体。本文采用实验要求比阴离子简单的阳离子聚合方法,用对-氯甲基-β-溴乙苯和三更多还原

【Abstract】 The synthesis of PS macromer with the method of cationic polymerization was studied. Styrene monomers was initiated by BrCH2CH -CH2Cl/AlEt3 and thePs macromer with narrow MWD(1.4) was obtained. Under certain extent, the mole. cular weight of the Ps macromer can be controlled. The Ps macromer with structureCH3=CH - CH2-Ps was characterized by UV spectra and GPC. They werecopolymerized with ethylene and propylene and vinyl acetate. The products of copo-lymerization were graft copolymers EP-g-Ps and PVac-g-Ps.更多还原
