摘　　要：介绍了采用"两步法"合成醋酸丁酸纤维素(CAB)与丙烯酸羟乙酯/己内酯加合物(PCLA)的接枝共聚物的制备方法,比较了改性前后CAB性能的变化。结果表明:引入长链线性基团,提高了醋酸丁酸纤维素的柔韧性;预聚物按取代CAB中的90%羟基投料反应时,接枝共聚物涂膜的综合性能优良。This paper introduces the preparation of copolymers （CDA-g-PCLA） of cellulose acetate-butyrate （CAB） grafting polycaprolactone monoacrylate （PCLA） by two-step method;and compares the differences of the properties of CAB before and after grafting modification,showing that the introduce of long-chain linear groups can improve the flexibility of CAB;and feeding material to substitute 90%,of hydroxyl can give graft copolymer with perfect comprehensive film properties.
