利用熔融缩聚的方法将N-甲基二乙醇胺与丁二酸和1，4-丁二醇共聚，制备含N的聚丁二酸丁二酯(PBS)共聚物(N–PBS)，然后将其与纤维素衍生物羟乙基纤维素(HEC)进行溶液共混，制备了在水相中均匀分散的共混乳液，用流延成膜法制备了N–PBS／HEC共混膜。研究了N–PBS中—N(CH3)—基团的含量对N–PBS亲水性及共混膜性能的影响。结果表明，随着N–PBS中—N(CH3)—含量的增加，N–PBS极性增加，亲水性增强；相对于PBS，N–PBS与HEC的相容性得到改善，共混膜的热分解温度在300℃以上，热稳定性良好，其透过率和断裂伸长率也随着N–PBS中—N(CH3)—含量的增加而提高。

Polybutylene succinate (PBS) copolymer containing nitrogen(N) (N–PBS) was prepared by the method of melt polycondensation through copolymerization of N-methyl diethanolamine,succinic acid and 1,4-butylene glycol. The homogeneous blending emulsions were prepared by mixing N–PBS and hydroxyethyl cellulose (HEC) in solution and N–PBS/HEC blending film was prepared by film casting. It was aimed to discuss the effects for introduction of N-containing functional group [—N(CH3)—] into the main chain of PBS,including the effects on the hydrophilicity of N–PBS and properties of N–PBS/HEC blending film. The results show that the polarity of N–PBS increases with the increase of the N-containing functional group content in N–PBS, meanwhile,the hydrophilicity of N–PBS increases. Comparing with PBS,the compatibility between N–PBS HEC is improved. The thermal property of N–PBS/HEC blending film is good with the decomposition temperature being above 300℃. The transmittance and elongation at break of the film all increase with the increase of the N-containing functional group content in N–PBS.
