Abstract

A new novolac curing agent with an alkoxysilyl group exhibiting excellent heat resistance such as a low CTE and an high Tg when a composite is formed, a preparing method of the same, a composition including the same, a cured article, and an use thereof, are provided. The new novolac curing agent having an alkoxysilyl group of Formulae I-1 to I-4, a preparing method of the new novolac curing agent by alkenylation and alkoxysilylation of the novolac curing agent, a preparing method of the new novolac curing agent by alkoxysilylation of a novolac curing agent, a composition including a novolac curing agent having an alkoxysilyl group of Formulae I-1 to I-4, a cured article and a use thereof, are provided. A composite including a novel novolac curing agent having an alkoxysilyl group exhibits a low CTE and a high glass transition temperature.
