    摘要： A method for producing liquid isocyanurate modified Polymeric MDI composition containing a high two-ring MDI content, and foams made therefrom is described. The method comprises trimerizing a polymeric MDI in the presence of catalytically effective amount of a trimerization catalyst to form an isocyanurate containing polyisocyanate having a viscosity of about 100,000 mPas. The trimerization catalyst is thereafter deactivated and the isocyanurate-modified polyisocyanate is blended with a methylene bis(phenylisocyanate) (MDI) to form a final product having a two-ring content of about 60 percent of the total ring content and a viscosity comparable to polymeric MDI. Foams produced using this liquid isocyanurate modified polymeric MDI are of a substantially lighter color than those produced from standard polymeric MDI.
