A new kind of polyesteramide based on 3-morpholinone and e caprolactone was synthesized by ring opening polymerization with zinc powder as catalyst.The polymer was characterized by^(1)H NMR,GPC and FT-IR.The effect of time,temperature and ratio of m(M)/m(1),n(M)/n(CL)on the reaction was studied.The results show that the optimal reaction temperature is 120℃;the optimal duration of reaction is 24 h;the optimal ratio of m(M)/m(CL)is 50:1;the optimal ratio of n(M)/n(CL)is 1:2.Under the optimal condition the polymer whose M_(n)was 13509 could be obtained while the weight yield was 79%. 展开更多
