Carbodiimide-isocyanurate foams containing urethane linkages |
| abstract |
Cellular foam compositions are prepared by catalytically condensing an organic polyisocyanate in the presence of a blowing agent, from 0.01 to 0.5 equivalent per equivalent of isocyanate of a primary hydroxy-terminated polyoxyalkylene or polyester polyol and a catalyst system comprising (a) methanol, (b) a tertiary amine trimerization catalyst, and (c) a urethane catalyst. The resulting foam compositions are characterized by carbodiimide, isocyanurate and urethane linkages and exhibit unexpectedly low friability, improved strength properties, and good flame retardancy. |
