Abstract
1493120 Polyurethane foams BRIDGESTONE TIRE CO Ltd 24 Dec 1974 [25 Dec 1973] 55707/74 Heading C3R Polyurethane foams are prepared by reacting, in the presence of an alkaline earth metal salt of a carboxylic acid and a foaming agent, a polyisocyanate with a mixture of (a) a polyol whose hydroxyl groups comprise more than 50% secondary hydroxyl groups and which has a number average molecular weight of at least 3000 and (b) a low molecular weight polyhydroxyl compound, in which the equivalent ratio of the low molecular weight polyhydroxyl compound to the polyol ranges from 0À5 to 2À0. Preferred alkaline earth metal salts are the barium salts of aliphatic carboxylic acids, e.g. barium acetate, barium 2-ethylcaproate or barium stearate. In the example, a polyurethane foam is prepared from a mixture comprising a poly(oxypropylene) triol, trimethylolpropane, tolylene diisocyanate, barium 2-ethyl caproate, water and a polysiloxane foam stabilizing agent.
