POLYOL COMBINATION

摘要

Polyol combination comprising up to a total of 100 parts by weight of (1) 1 to 15 parts by weight of a polyalkoxylated monol having a number average molecular weight in the range of from 400 to 4000, (2) 50 to 97 parts by weight of a polyalkoxylated diol having a number average molecular weight in the range of from 1000 to 7000, and (3) 2 to 40 parts by weight of a polyoxyalkylated polyol having solid polymer particles stably dispersed therein (herinafter referred to as "polymer polyol"), which polyoxyalkylated polyol has a nominal functionality of at least 3; a formulation for preparing a foam comprising such polyol combination and a process of preparing a viscoelastic high resilience polyurethane foam with the help of such polyol combination.
