Synthesis of polyureas by polycondensation of diamines with active derivatives of carbonic acid
Abstract New polycondensation reactions of active diphenyl carbonates and diphenyl carbamate with diamines were developed for the synthesis of high‐molecular‐weight polyureas. The kinetics and mechanism of carbonic acid active esters aminolysis model reactions were studied. Possible side reactions i...
