ABSTRACT:
A modified polyisocyanurate foam is produced by reacting an organic polyisocyanate, a polyol and water in the presence of three catalyst, i.e. two particular trimerization catalysts and a carbodiimidation catalyst. There can be produced, without using any evaporating type blowing agent, a modified polyisocyanurate foam which is suitably used for continuous production of laminate boards, siding boards, insulation boards, etc.
