Abstract: A material design apparatus is provided that can derive an optimal solution of a design condition of a polymer that satisfies desired and required physical properties. A material design apparatus 1 includes a blend proportion range input unit 11 configured to set a specified range of a design condition of a polymer, a comprehensive analysis point generation unit 12 configured to generate multiple comprehensive analysis points within the specified range input in the blend proportion range input unit 11, a comprehensive analysis point-polymer physical property value storage unit 14 configured to input the comprehensive analysis point generated in the comprehensive analysis point generation unit 12 into a learned model 13 to calculate a physical property value of a polymer and to store a data set in which the physical property value of the polymer and each point of the comprehensive analysis point are linked, a required physical property input unit 21 configured to set a specified range of a required physical property of a polymer material to be designed, and a filter unit 22 configured to select a comprehensive analysis point that satisfies the required physical property input in the required physical property input unit 21 from the data set stored in the comprehensive analysis point-polymer physical property value storage unit 14.

Abstract: A polyisocyanurate raw material composition containing a polyfunctional isocyanate, a compound (I) represented by general formula (I) shown below, and an epoxy compound. In general formula (I), each of R1 to R5 represents a hydrogen atom, an alkoxy group of 1 to 10 carbon atoms, an alkyl group of 2 to 10 carbon atoms (or an alkyl group of 1 to 10 carbon atoms in the case of R3 to R5), an aryl group of 6 to 12 carbon atoms, an amino group, a monoalkylamino group of 1 to 10 carbon atoms, a dialkylamino group of 2 to 20 carbon atoms, a carboxy group, a cyano group, a fluoroalkyl group of 1 to 10 carbon atoms, or a halogen atom (provide that R1 and R2 are not both hydrogen atoms).
