摘要: 本文报道了以带有烯丙基端基的聚氧乙烯大分子单体为中间体,制备聚丙烯酸-g-聚氧乙烯共聚物的方法。通过用模型实验证实了合成得到的聚合产物系由大分子单体的端功能基与小分子共聚单体作用所致后,将产物进行纯化处理,并建立了红外光谱法测定该共聚物体系组成的方法。对影响共聚的若干因素进行了试验。另外,对所得共聚物的溶液行为也进行了初步考察。

Abstract: Copolymerization of allyl group-capped PEOmacromers with acrylic acid co-monomer to obtain a new type of graft copolymer(PAA-g-PEO) was reported. With the help of model test it is illustrated that the obtained polymer is of the expected structure. A method to determine the composition of copolymer based on IRspectrometry has been set up. Several effects on the copolymerization were examined and the specific solution-behavior was also reported.
