摘　　要：合成了烯丙氧基苯甲酸对苯二酚酯的衍生物．（ＡＢＰ），用ＮＭＲ及ＭＳ对其结构进行了鉴定。以含氢硅油作主链与烯丙氧基苯甲酸对苯二酚酯衍生物（ＡＢＰＲ）通过氢的加成反应合成了侧链含ＡＢＰＲ的聚硅氧烷。用红外光谱证明，大部分Ｓｉ－Ｈ已参加了反应。聚合物具有液晶性。A new technique of covalent bonding of polymethaerylic acid onto heparin was described. The reaction involved free radical polymerization of methacrylic acid (MAA) initiated by tetravalent cerie ion in aqueous solution and crosslinked with ethylene glycol dimethacrylate.The characteristics on the grafting reaction and the resulting polymer were studied. The antithrombogenicity of the crosslinked polymer was tested. The preliminary results showed that these copolymers are of excellent antithromboresistance and may be interesting for medical applications.
