Abstract
1386399 Isocyanurate polymers IMPERIAL CHEMICAL INDUSTRIES Ltd 23 June 1972 [16 July 1971] 33459/71 Heading C3R Isocyanurate polymers are obtained by contacting 3 - isocyanatomethyl - 3,5,5 - trimethylcyclohexyl isocyanate with an alkali metal phenate catalyst at an elevated temperature. In examples isocyanurate polymers are obtained by heating the diisocyanate with sodium phenate, sodium p-methoxy-phenate and sodium p-tert. butylphenate in solvents.
