摘　　要：用对氨基偶氮苯和丙烯酰氯合成了侧链上含有偶氮苯基的单体,并用此单体与丙烯酸(AA)共聚制备了一种新型的响应型高分子,对高分子的pH和光响应性进行了研究．结果表明,共聚高分子显示出较好的 pH和光响应性,且响应性随共聚比例不同而改变,这种双重响应性分别与共聚高分子结构中的羧基解离和偶氮苯基发生顺-反异构有关．A monomer with a side-chain azobenzide AAAB was synthesized, and a series of new polymers P （AA-co-AAAB） were synthesized by radical copolymerizing the AAAB monomer with acrylic acid （AA）. Their sensibilities in response to pH and ultraviolet light were studied. It was found that these copolymers show a good pH and photo responsivities and this responsivities were caused by the ionization of carboxyland and cis-trans isomerism of azobenzide, respectively.
