【Task】 The present invention relates to a novolac curing agent having an alkoxysilyl group, which exhibits excellent heat resistance characteristics such as a low coefficient of thermal expansion (CTE) and a high glass transition temperature when forming a composite, and a method for producing the same , Compositions containing the same, cured products, and uses thereof. [Solution] According to one embodiment of the present invention, novolak curing agents having alkoxysilyl groups of formulas I-1 to I-4, alkenylation of novolac curing agents and alkoxysilyl groups of formulas I-1 to I-4 by alkoxysilylation Of novolak curing agents having formulas, novolak curing agents having alkoxysilyl groups of formulas I-1 to I-4 by alkoxysilylation of novolak curing agents, alkoxysilyl groups of formulas I-1 to I-4 A composition comprising a novolac curing agent having: a cured product thereof; and a use. The composite containing the novel novolak curing agent having an alkoxysilyl group according to the present invention is not only a chemical bond between the alkoxysilyl group of the curing agent and the filler, but also a chemical bond between the alkoxysilyl group of the curing agent and the phenol or epoxide group. Shows a low CTE and a high glass transition temperature. [Selection] Figure 1 |
