NEW EPOXY COMPOUND HAVING ALKOXYSILYL GROUP, PREPARING METHOD THEREOF, COMPOSITION, CURED PRODUCT THEREOF, AND USES THEREOF

摘要

The present invention relates to a novel epoxy compound, a preparing method thereof, a composition containing the same, a cured product, and a use thereof, wherein the epoxy compound having a spacer between a core and an alkoxysilyl group exhibits excellent heat-resistant properties and, more specifically, a low coefficient of thermal expansion and a high glass transition temperature (which includes Tg-less which does not exhibit glass transition temperature) and an improved brittleness in a composite and/or excellent flame retardant characteristics in a cured product. According to the present invention, provided are an epoxy compound having at least one alkoxysilyl group which has passed through a spacer group which has at least two epoxy groups, at least one alkoxysilyl group, and a predetermined number of hydrogen, hydroxy groups and/or alkenyl groups; a preparing method thereof, which includes a step of receiving a spacer group and an epoxy group and an alkoxysilylation step; a preparing method thereof, which includes a step of receiving a spacer group and an epoxy group, an alkenylation step and an alkoxysilylation step; a composition containing the epoxy compound; a cured product; and a use thereof. The epoxy composition containing the epoxy compound with the alkoxysilyl group which has passed through the spacer group according to the present invention exhibits improved heat-resistant properties, i.e. effects of reducing CTE, increasing glass transition temperature or exhibiting no glass transition temperature (hereinafter referred to as′Tg less′) in a composite. Furthermore, the epoxy compound exhibits improved brittleness. Moreover, the cured product of the epoxy composition containing the epoxy compound with the alkoxysilyl group which has passed through the spacer group according to the present invention exhibits excellent flame retardant properties due to introduction of the alkoxysilyl group.
