In biomedical applications, a typical TPU consists of PTMO as soft segment and diisocyanatodiphenyl methane as a hard segment. Further, 1,4-butanediol is used as a chain extender (37). [Pg.159]

Curing of the acetylenic polyacetals to rubbery polyurethanes could be achieved with any of a number of commercially available diisocyanates, including 2,4-toluene diisocyanate (TDI), hexamethylene diisocyanate (HDI), dianisidine diisocyanate (DADI), and 4,4 -diisocyanatodiphenyl-methane (MDI). The first two diisocyanates were studied most extensively. The reactions were carried out in solution in benzene, toluene, and ethylene bromide, and in bulk. The bulk reaction, which is the only... [Pg.128]
