Abstract
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° C. and 150° C. and an amino equivalent to carboxylic equivalent of 0.3:1 to 50:1.
