    Abstract: The process involves reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and optionally c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents e) catalysts and optionally f) assistants and/or additives, where the blowing agents (d) used are at least one organic carboxylic acid, preferably an aliphatic monocarboxylic acid, optionally in combination with water and/or a physical blowing agent, and where the catalysts (e) used are polyisocyanurate catalysts, preferably alkali metal or ammonium salts of organic carboxylic acids or tris(dialkylaminoalkyl)-s-hexahydrotriazines.

    Abstract: This invention relates to an urethane group containing polyisocyanurate foam produced from a polyisocyanate and a polyhydroxy compound, wherein the polyhydroxy compound is the reaction mixture of a hydroxyl group containing amine which is at least difunctional and is selected from the group consisting of a secondary amine, a tertiary amine, and a mixture thereof, and a naphthenic acid, or a mixture of said reaction mixture and a conventional polyol, the reaction conditions are a temperature between 0 DEG C. and 150 DEG C. and an amino equivalent to carboxylic equivalent of 0.3:1 to 50:1.
