A series of eight thermoplastic polyurethane elastomers were synthesized from 4,4'-methylene diphenyl diisocyanate (MDI) and 1,4-butanediol (BDO) chain extender, with poly(hexamethy1ene oxide) (PHMO) macrodiol soft segments. The soft segment molecular weights employed ranged from 433 g/mol to 1180 g

## Abstract In this study, a series of nonionic waterborne polyurethanes containing side chain poly(ethylene glycol) monomethyl ether (PEGME) were synthesized using 4,4βmethylene bis(isocyanatocyclohexane), the nonionic dispersing center produced by isophorone diisocyanate, __N__βdiethanol amine, a
## Abstract A series of segmented polyurethanes (SPUs) containing various polyol soft segments was prepared and their resistance to oxidative degradation was investigated after aging in AgNO~3~ solution. The SPU with the polyether soft segment showed a large reduction in mechanical strength after e
## Abstract The effect of softβsegment chemistry on biostability of polyurethane elastomers was studied with a diaphragmβtype film specimen under conditions of static and dynamic loading. During testing, the films were exposed to an H~2~O~2~/CoCl~2~ solution, which simulated the oxidative component
