Polyether PolyolsA na-eme ya site na mmeghachi omume organic oxide na glycol.

Isi organic oxide etinyere bụEthylene oxide,Propylene oxide,Butylene oxide,Epichlorohydrin.

A na-eji glycol bụ isiEthylene glycol,Propylene glycol,Mmiri,Glycerin,Sorbitol,Sucrose,THME.

Polyols nwere otu reactive hydroxyl (OH) nke na-emeghachi omume na otu isocyanate (NCO) na isocyanates iji mepụta polyurethane.

E nwere ọtụtụ ụdị polyether polyols makapolyurethane.Enwere ike nweta ihe PU nwere arụmọrụ dị iche iche site na mmeghachi omume n'etiti ndị mmalite dị iche iche na olefin polymerization.

Site n'ịgbanwe ngwa ngwa PU ma ọ bụ ịgbanwe ihe na-akpali akpali, enwere ike gbanwee arụmọrụ polyether.Ndị mbido a gụnyere mmanya diethyl, mmanya ternary, tetrahydrofuran, na aromatic polyether polyols, wdg.
