Polyether Polyol yog dab tsi

Polyether polyol (abbreviated li polyether) yog ib qho organic polymer tsim los ntawm kev sib ntxiv cov tshuaj tiv thaiv ntawm ib qho kev pib (ib qho chaw uas muaj active hydrogen pawg) nrog ethylene oxide (EO), propylene oxide (PO), thiab butane oxide (BO) nyob rau hauv muaj. ib catalyst. Qhov loj tshaj plaws ntawm polyether yog ua tiav los ntawm kev siv glycerol (glycerol) ua tus neeg sawv cev pib thiab epoxides (feem ntau yog siv ua ke nrog PO thiab EO). Los ntawm kev hloov txoj kev pub mis (sib xyaw lossis sib cais), qhov sib piv ntau npaum li cas, thiab kev txiav txim pub mis ntawm PO thiab EO, ntau yam universal polyether polyols raug tsim.
