Abstract
Modified polyols having the formula R.sub.m SiXx.sub.4-m wherein m=1 to 3, X is an alkoxy group and at least one R group is either HS--R.sup.1 -- or HS--(SiR.sup.2.sub.2 O).sub.n -- are described. The modified polyols, when mixed with base polyol, are used in the manufacture of graft polymer polyols having low viscosity and good filtrability. The graft polymer polyol can be used in the manufacture of polyurethane foam.
