    摘要: The present invention relates to a novolac hardener having an alkoxysilyl group, the novolac hardener exhibiting excellent heat resistance characteristics, such as a low coefficient of thermal expansion (CTE) and an increase in the glass transition temperature, when forming a composite; a method for preparing the same; a composition containing the same; a hardened product; and a use thereof. According to an embodiment of the present invention, provided are a novolac hardener having an alkoxysilyl group of chemical formulas I-1 to I-4; a method for preparing the novolac hardener having an alkoxysilyl group of chemical formulas I-1 to 1-4 through alkenylation and alkoxysilylation of the novolac hardener; a method for preparing the novolac hardener having an alkoxysilyl group of chemical formulas I-1 to 1-4 through alkoxysilylation of the novolac hardener; a composition containing the novolac hardener having an alkoxysilyl group of chemical formulas I-1 to I-4; a hardened product thereof; and a use thereof. A composite comprising the novel hardener having an alkoxysilyl group according to the present invention exhibits a low CTE and a high glass transition temperature through a chemical bond between the alkoxysilyl group of the hardener and a phenol or epoxide group as well as a chemical bond between the alkoxysilyl group of the hardener and a filler.
