通过双恶唑啉 1a – 1f 和双恶嗪 2a 和 2b 与二硫醇 3a – c 在非质子极性溶剂中的加成反应合成了具有酰胺和硫醚键的交替共聚物。芳香族双官能环状亚氨基醚如1a、1c、2a和2b与二硫醇3a和3c在N-甲基-2-吡咯烷酮中反应得到高分子量的聚合物。然而，脂肪族衍生物如1e和1f与二硫醇的反应以及双官能环状亚氨基醚与3b的反应导致产生低分子量的聚合物。甲基取代的双恶唑啉1b和1d与二硫醇的反应也得到低分子量的聚合物。
Alternating copolymers with amide and thioether linkages were synthesized by addition reactions of bisoxazolines 1a – 1f and bisoxazines 2a and 2b with dithiols 3a – c in aprotic polar solvents. The reactions of the aromatic bifunctional cyclic iminoethers such as 1a, 1c, 2a, and 2b with the dithiols 3a and 3c in N-methyl-2-pyrrolidone gave polymers with high molecular weight. However, the reactions of the aliphatic derivatives such as 1e and 1f with dithiols as well as the reactions of the bifunctional cyclic iminoethers with 3b led to polymers of low molecular weights. The reactions of methyl substituted bisoxazolines 1b and 1d with dithiols gave also polymers of low molecular weight.
