From conformational analysis, we have determined the two lowest energy crystal structures for the hard segments of 4,4ะˆ-diphenylmethane diisocyanate/1,4butanediol (MDI/BDO)-based polyurethane elastomer. Both crystal forms give prominent X-ray scattering at ฯณ7.6 ร…. In one crystal form, (1), there is
