摘要: Micro-Raman spectroscopy has been used to investigate the chemical micro-heterogeneity of multiphase-separated poly(ether urethanes) (PETU). Analysis PETU cross-sections by means micro-Raman revealed nearly complete absence soft segments in Al aggregates (called globules). These are order a few micrometers size. The composition matrix and AII (spherulites) was comparable.
