STYVA, MEDELST URETAN MODIFIERADE ISOCYANURATSKUM OCH FOERKOMPOSITION, VILKEN KAN ANVAENDAS VID FRAMSTAELLNING AV DESSA |
摘要 |
The invention relates to isocyanate-derived foams and a precursor composition. The foam comprises the reaction product of a polyisocyanate and at least two active hydrogen-containing compounds reactive with an isocyanate, one of them being an alkylene oxide polymer having an equivalent weight of at least 300 and being composed of at least about 10 weight percent of a polymerized ethylene oxide-based on total weight of the polymerized alkylene oxide in the polymer. The precursor composition comprises said alkylene oxide polymer and a compound containing at least two active hydrogens reactive with an isocyanate. |
