    摘要: Isocyanurate polyisocyanates compositions derived from bis(isocyanotomethyl)cyclohexane are disclosed. The compositions are prepared by cyclizing (i) 1,3-bis(isocyanotomethyl)cyclohexane or 1,4-bis(isocyanotomethyl)cyclohexane or (ii) an isomeric mixture of two or more of cis-1,3-bis(isocyanotomethyl)cyclohexane, trans-1,3-bis(isocyanotomethyl)cyclohexane, cis-1,4-bis(isocyanotomethyl)cyclohexane and trans-1,4-bis(isocyanotomethyl)cyclohexane in the presence of a trimerization catalysts, and then deactivating these catalysts. The isocyanurate polyisocyanates can be further modified to contain urethane, urea, biuret, allophanate, imino-s-triazine, uretonimine or carbodiimide moieties.
