FLAME-RETARDANT POLYOL COMPOSITION FOR SOFT POLYURETHANE FOAM, AND FLAME-RETARDANT POLYURETHANE FOAM COMPOUNDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition excellent in flame retardancy and storage stability and useful as a constituent material for automotive interiors, etc., by including a specific bromine compound, tris(2,3-dibromopropyl) isocyanurate, etc., and a polyol. ;SOLUTION: This flame-retardant polyol composition is obtained by homogeneously dissolving or dispersing (A) a bromine compound of formula I [A is 2,2- propylene, etc.; R is H, etc.; (n), (m) are each independently an integer of 1-5), such as 2,2-bis[4-(2hydroxyethoxy)-3,5-dibromophenyl]propane and (B) tris(2,3 dibromopropyl)isocyanurate or a compound of formula II, e.g. 2,2bis[3,5- dibromo-4-(2,3-dibromopropoxy)phenyl]propane in (C) a polyol (glycerol, an alkanolamine, etc.), heated at 50-150°C in a total amount of 5-80 wt.% based on the polyol.;COPYRIGHT: (C)1999,JPO
