From conformational analysis, we have determined the two lowest energy crystal structures for the hard segments of 4,4Π-diphenylmethane diisocyanate/1,4butanediol (MDI/BDO)-based polyurethane elastomer. Both crystal forms give prominent X-ray scattering at Ο³7.6 Γ . In one crystal form, (1), there is

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
Mechanical and dielectric properties of two series of segmented polyurethanes having soft segment concentration of 50 and 70% and a varying degree of crosslinking through the hard segment were studied. The degree of crosslinking in each series was varied by varying the butane diol/trimethylol propan
