    摘要： The present invention provides a solventless, continuous process, which includes: in at least one extruder, intensive compounder, intensive mixer or static mixer, mixing and heating a reaction mixture including the following (A), (B), and one or both of (C) and (D): (A) at least one aliphatic, (cyclo)aliphatic and/or cycloaliphatic C3-C50 diisocyanate compound; (B) at least one aliphatic, (cyclo)aliphatic and/or cycloaliphatic C3-C50 polyisocyanate compound containing one or more isocyanurate groups; (C) 1,2,4-triazole; (D) one or more pyrazole having the formula: where R1, R2 and R3 simultaneously or independently of one another are hydrogen or alkyl, alkenyl, aralkyl, aryl or N-substituted carbamoyl groups, halogen or —C(═O)—O—R4, where R4 is a C1-C12 alkyl group; to obtain a product mixture including at least one (semi)crystalline, blocked C3-C50 isocyanate compound and at least one amorphous, blocked C3-C50 isocyanate compound. The present invention also provides a composition prepared by the process and methods of using the composition.
