## Abstract Two series of poly(ether urethane)s and one series of poly(ester urethane)s were synthesized, containing, respectively, poly(oxytetramethylene) diol (PTMO) of __M__~__n__~ = 1000 and 2000 and poly(Ξ΅βcaprolactone) diol of __M__~__n__~ = 2000 as soft segments. In each series the same hard
To enhance the thermal properties of ultrahigh molecular weight (UHMW) (viscosity-average molecular weight of 6 1 10 6 ) polyethylene (PE) gel film, this was crosslinked by dicumyl peroxide (DCP) during a high-temperature zone drawing, which is effective to orient film. Through a series of experimen
