| 摘 要： | <正> 用亲水性单体对嵌段聚醚氨酯(SPEU)膜接枝共聚以改善其抗凝血性能,在医用材料的研究中已引起普遍重视,但由于一般化学方法接枝引发系统中带入的小分子常常对产品的医用性质造成不利的影响。我们曾报道通过Co~(60)-γ射线预辐照法用亲水性单体对以PTMG;MDI与不同的二胺类扩链剂制备的SPEU膜接枝共聚。本文在此基础上选用了两种单体AMP和MAMP。

| Abstract: | The graft copolymerization of N-methacryl-N'-methyl-opiperazine onto segmented polye-therurethane (SPEU) film by Go60-r-preirradiation has been studied. It is found that the grafting time varies with structure of different chain extenders. The grafted substrated become opaque, the contact angle drops down and from SEM photographs with salient micrograph showing grafts of macrochain on the surface of SPEU film. |
