In polyether component (a) preferably at least 10% wt. of the OH groups are primary OH groups. Part of the polyether component (a) may be replaced by compounds ofM.Wt. 800 to 10,000 containing NCO-reactive hydrogen atoms, e.g. polyesters, polyamines, polythiols, polycarboxylic acids, polyacetals, polycarbonates and OH-containing polybutadienes. The dihydric alcohol (b) may be a C2-C8 alkane diol, 1,4-bis-hydroxymethylcyclohexane, di-, tri-, tetra- or poly-ethylene, – propylene or -butylene glycols. The blowing agent may be water and/or a volatile inert organic substance. Suitable trimerization catalysts include quaternary ammonium hydroxides, alkali metal hydroxides, alkali metal alkoxides, alkali metal salts of carboxylic acids, lead octoate and certain tertiary amines, e.g. N-(2- dimethyl-aminoethyl)-N<1>-methyl piperazine and tris – (3 – dimethylaminopropyl) – hexahydrotriazine. The above catalysts may be used together with conventional urethane catalysts. Conventional additives such as foam stabilizers, cell regulators and stabilizers may be added. The process is preferably carried out by the oneshot procedure and it may be carried out continuously or discontinuously. The cell diameter of the foam is generally from 0À3 to 2À5 mm. Thermoforming of the foam may be carried out by bending, pressing or stamping and the heating may be carried out in hot air ovens, microwave or infra-red heating channels or contact hot plates. The thermoforming temperature is generally from 150 to 210 C. The thermoforming may be carried out continuously or discontinuously and the foam may be profiled. In a typical example a rigid polyisocyanurate foam is prepared by vigorously mixing a component (A) comprising an ethylene oxide/propylene oxide/trimethylolpropane polyether of OH number 56, ethane-1,2-diol, water, tris – (dimethylaminopropyl) -hexahydrotriazine, potassium acetate, permethylated diethylenetriamine, a polyether polysiloxane stabilizer and a phenylmethyl polysiloxane cell regulator, with a component (B) comprising monofluorotrichloromethane and diisocyanatodiphenylmethane consisting of 90% wt. of 4,4<1>-isomers and 10% wt. of 2,41-isomers modified with 14% wt. of tripropylene glycol.
