## Abstract The phase‐separation behavior and morphology of polycarbonate‐based polyurethanes were investigated as a function of the soft‐segment molecular weight and chemical structure and the 4,4′‐diphenylmethane diisocyanate/1,4‐butanediol based hard‐segment contents. Polarized optical microscop

Two series of segmented polyurethanes, one containing 50% soft segments and the other with 70% soft segments were synthesized. Chemical crosslinks were introduced through the hard segment in a controlled way. Chemical polyurethane networks were characterized by swelling. The effect of the degree of
## Abstract Two series of poly(ether urethane)s and one series of poly(ester urethane)s were synthesized, containing, respectively, poly(oxytetramethylene) diol (PTMO) of __M__~__n__~ = 1000 and 2000 and poly(ε‐caprolactone) diol of __M__~__n__~ = 2000 as soft segments. In each series the same hard
