PCT No. PCT/CH91/00061 Sec. 371 Date Jan. 21, 1992 Sec. 102(e) Date Jan. 21, 1992 PCT Filed Mar. 18, 1991 PCT Pub. No. WO91/14731 PCT Pub. Date Oct. 3, 1991.Stable, emission-free, low-shrinkage, fireproof aminoplastic cellular foams are obtained by using an unsaturated, halogenated polyalcohol in the resin precondensate constituent and a dodecylbenzolsulphonic acid partially esterified preferably with a fatty alcohol and a long-chain polyhydric alcohol, preferably a polyethylene glycol, in the foaming agent hardener consituent. The foams are particularly suitable for building construction and for covering, as well as in the agricultural sector and or oil absorption. For certain of these applications, the resin pre-condensate constituent of the invention can be processed with a conventional foamer hardener constituent or the foamer hardener constituent of the invention can be processed with a conventional resin precondensate constituent. |
