Document Type and Number:
Japanese Patent JP6324908
Kind Code:
B2
Abstract:
Method for producing a rigid polymeric foam, comprising the conversion of components A to C in the presence of component D or an isocyanate group-containing pre-polymers of components A and B with component C in the presence of component D, the total quantity of which is 100% by weight, (A) 35 to 65% by weight of at least one polyisocyanate component A, (B) 5 to 50% by weight of at least one polyol component B, (C) 1 to 59% by weight of at least one polycarboxylic acid component C and (D) 0.01 to 3% by weight of at least one Lewis base component D, wherein conversion takes place with the release of carbon dioxide.
