ABSTRACT:
New catalysts for isocyanurate foams are those comprising aminomethacrylate salts. The foams are obtained by the polymerization of an aromatic polyisocyanate, and a polyether or polyester polyol in the presence of a blowing agent and said amino methacrylate salts falling within the following structural formula: ##STR1## where the radicals represented by R are hydroxy lower alkyl, and M is selected from the group consisting of sodium, potassium, cesium, lithium and rubidium. The novel foams are useful in preparing rigid, flexible, semi-rigid, or semi-flexible materials such as panels, slabs or sprayed foam surfaces.
