摘要

Polyurethane elastomers derived from 4

4'-methylene bis(phenyl isocyanate)

butylene glycol and the lowoxyethylene moiety content copolyether of tetrahydrofuran and ethylene oxide

obtained by copolymerization usingheteropolyacid-ethylene oxide initiator system

were prepared. The polyurethanes exhibited an increased water absorptionand much better low temperature resilience

which remained high even at a temperature of -3℃

while that of polyurethanebased upon poly(tetramethylene ether) glycol of the same molecular weight

i.e. being 2000

and molecular weight distribution

i.e.in the range of 1.4-1.5

starts to decrease dramatically at 5℃.
