摘　　要：用13CNM R方法研究了丙烯酸及丙烯腈对多肽分子接枝共聚功能化修饰机理,发现经功能化修饰后的接枝共聚物在δ=69.6、44.1~44.5处有特征共振峰.功能化修饰是引起多肽分子的皮革复鞣填充性能明显改善的主要原因.The functional modification mechanism of acrylonitrile to the graft copolymerization of polypeptide was studied by ^13CNMR. The results of ^13CNMR showed that the characterized absorptions of graft copolymers appeared at δ=69.6 and 44. 1-44.5. The functional modification of polypeptide was the main reason of obvious improvement in retanning and fullness properties of leather.
