We report the structure and properties of segmented poly(urethaneurea) (SPUU) with relatively short hard-segment chains. The SPUU samples comprised poly(tetramethylene glycol) prepolymer as a soft segment and 4,4Π-diphenylmethane diisocyanate (MDI) units as a hard segment that were extended with eth
Novel, segmented thermoplastic silicone-urea (TPSU) copolymers based on rather high molecular weight aminopropyl terminated polydimethylsiloxane (PDMS) soft segments ( 10,800 and 31,500 g/mol), a cycloaliphatic diisocyanate (HMDI) and various diamine chain extenders were synthesized. Copolymers with
