Abstract: Provided herein is a process for producing viscoelastic polyurethane foams having a density of from 100 g/dm3 to 300 g/dm3, in which (a) polyisocyanate is mixed with (b) polymeric compounds having groups that are reactive toward isocyanates, (d) a catalyst, and (e) a blowing agent including water at an isocyanate index of from 50 to 95 to give a reaction mixture. The reaction mixture is placed in a mold and reacted to give the flexible polyurethane foam, wherein the polyisocyanate (a) is obtainable by mixing 4,4′-MDI and oligomers of propylene oxide having from 2 to 8 propylene oxide units. The polymeric compounds (b) include at least one polyalkylene oxide having a hydroxyl number of from 20 to 50 mg KOH/g derived from a trifunctional starter molecule and a proportion of ethylene oxide, based on the content of alkylene oxide, of from 0 to 10%.

Abstract: A graft macromer, comprising the reaction product of at least one macromer being at least one molecule which comprises in its structure one or more hydroxyl-terminated polyether and/or polyester chains, with at least one grafting compound which comprises in its structure at least one at least monoalkoxylated or at least monohalogenated silyl group and at least one alkyl, cycloalkyl or aryl containing group which is reactive towards the hydroxyl group of the macromer, is used for dispersing e.g. SiO2 in a polyol.
