Abstract
The present invention is a method for producing a thermal-shock-resistant cured product, the method involving: a condensation step of preparing a cured-product precursor by subjecting monomers represented by general formulae (1) to (5) to copolycondensation at a specific rate in the presence of an acid catalyst; and a curing step of curing the cured-product precursor by polymerizing at least a portion of ethylenically unsaturated bonds in the cured-product precursor. Also, the present invention is a cured product prepared by said method. (In formulae (1) to (5): (X) is a siloxane bond producing group; R1, R2, and R4 are each a group selected from among a hydrogen atom, an alkyl group, an aralkyl group, a cycloalkyl group, a cycloaralkyl group, an aryl group, and a group having an ethylenically unsaturated bond; R3 and R5 are each a group selected from among a hydrogen atom, an alkyl group, an aralkyl group, a cycloalkyl group, a cycloaralkyl group, and an aryl group; and at least one of R1, R2, and R4 is a group having an ethylenically unsaturated bond.)
