    Abstract: Prodn. of an opt. difficulty inflammable urethane gp. contg. polyisocyanurate froam material by reaction of organic polyisocyanates and polyols in the presence of catalysts and opt. blowing agents, and other additives, there is used a co-catalyst system consisting of: a (a) 1,3,5-tris-(N,N-dialkylaminoalkyl)-s-hexahydrotriazine; and (b) an organic mono- or polycarboxylic acid with 1-14C atoms a half ester of the polycarboxylic acid or a polyesterol with acid no. 4. Pref. 0.5-15 pts. of co-catalyst system is used per 100 pts. of organic polyisocyanate. Pref. the molar ratio of (a):(b) in the catalyst system is from 30:1 to 0.7:1. Using the co-catalyst system the cream-time and rise-time can be varied and the reactivity of the starting material and the mechanical and spatial conditions adjusted.

    Abstract: Stable, liquid, homogeneous solutions of isocyanurate-polyisocyanates containing amide and/or acylurea groups in monomeric diisocyanates and/or polyisocyanates which are free from amide, acylurea and/or isocyanurate groups, are obtained by reacting polybasic carboxylic acids with diisocyanates and/or polyisocyanates to give diisocyanates and/or polyisocyanates containing amide groups and/or acylurea groups, converting the diisocyanates and/or polyisocyanates containing amide and/or acylurea groups by trimerization and, optionally, polymerization, into isocyanurate-polyisocyanates containing amide and/or acylurea groups, and mixing the products with monomeric diisocyanates and/or polyisocyanates.
