Various segmented polyurethane materials with a polyurethane hard segment (HS) content of 40 wt % were prepared by bulk polymerization of a poly(tetramethylene ether) glycol with M n of 2000, 1,4-butanediol, and various diisocyanates. The diisocyanates used were pure 4,4Π-diphenylmethane diisocyanat
## Abstract Various segmented polyurethanes with a hard segment content of about 50 wt% were prepared from 4,4β²βdiphenylmethane diisocyanate (MDI), a poly(tetramethylene adipate) glycol with an __M__~n~ of 2000, and various combinations of aliphatic diols as chain extenders by a oneβshot, handβcast
The synthesis of a hydroxylated polyurethane, by reduction with diborane of the corresponding carboxylated polymer, is described. The starting polyurethane, of the segmented type, contains as chain extender dihydroxymethylpropionic acid. Various conditions for hydrogenation of the carboxy group have
