摘要:
The present invention relates to: an alkoxysilyl-based epoxy compound which does not require a separate silane coupling agent and exhibits outstanding heat resistance, and more specifically a low coefficient of thermal expansion (CTE) and a high glass transition temperature in a synergistic effect in a composite material; a composition and a cured article comprising same; a use for same; and a production method for an epoxy compound having an alkoxysilyl group. Accordingly, the present invention provides: an epoxy compound having an epoxy group and an alkoxysilyl group; and a composition comprising the epoxy compound together with a curing agent, a filler and/or a reaction catalyst or the like, and various uses for same including in a cured article and electronic components. According to the present invention, the novel epoxy composition comprising the epoxy compound having the alkoxysilyl group exhibits improved heat resistance, which is to say an effect whereby the CTE of the epoxy composite is reduced and whereby the glass transition temperature is elevated or a glass transition temperature is not exhibited (referred to hereinbelow as "Tg less"), because of chemical bond formation due to a chemical reaction of the alkoxysilyl group and the filler (fibres and/or particles) and a chemical reaction between alkoxysilyl groups, in the composite material and/or the cured article. Moreover, the cured article comprising the epoxy compound having the alkoxysilyl group according to the present invention exhibits outstanding flame retardancy due to the inclusion of the alkoxysilyl group.

摘要:
A production method by which an alkyldiol monoglycidyl ether can be efficiently produced without requiring a complex purification step is provided. A method for producing an alkyldiol monoglycidyl ether, including a step of reacting a vinyl ether-containing alcohol with an epihalohydrin to form a vinyl ether-containing glycidyl ether, conducting a devinylation reaction in the presence of an acid catalyst and water, and further conducting an acetal decomposition reaction by adding an acid aqueous solution.
wherein L, R 1 , R', and m are as defined in the specification. The cyclic compound of formula (1) is highly soluble to a safety solvent, highly sensitive, and capable of forming resist patterns with good profile. Therefore, the cyclic compound is useful as a component of a radiation- sensitive composition.
