ABSTRACT:
A process for preparing a slow-burning, low-smoking, high heat-distortion-temperature polyisocyanurate polymer and the polymer produced thereby, which process comprises reacting an MDI prepolymer with a caprolactone polyol in the presence of a trimerization catalyst, wherein the MDI prepolymer is prepared from an MDI having a functionality of about 2.4 or less, and particularly a 2.4 isomer, and with an ethylene-oxide-capped polypropylene oxide polyol, the process providing for the formation of a rigid, high heat-distortion RIM or an open-spray molded part.
