Divinylbenzylfluorene compounds and their manufacturing methods, curable resin compositions and cured products

Abstract

This invention provides a divinylbenzylfluorene compound that balances solubility in methyl ethyl ketone with a high melting point. The divinylbenzylfluorene compound of the embodiment is a compound represented by the following general formula (1), wherein R1, R2 and R3 in formula (1) independently represent hydrocarbon groups having 1 to 5 carbon atoms, a, b and c independently represent integers from 0 to 4, and the ratio of the two vinylbenzyl groups in formula (1) to the para-p,p-isomers is 20% to 50%.
