Abstract: Disclosed is a polybenzoxazime precursor and a method of preparing the same. The polybenzoxazime precursor is used to prepare a hardened material having improved thermal characteristics, having high thermal and flame-retardant characteristics while maintaining its excellent electrical characteristics, or having high thermal and electrical characteristics, thus being available for use in a copper clad laminate, a semiconductor encapsulate, a printed circuit board, an adhesive, a paint, and a mold.

Abstract: This invention relates to a polybenzoxazine precursor and a method of preparing the same, and more particularly, to a polybenzoxazine precursor which includes benzoxazine obtained by reacting a phenol novolak resin with an aldehyde compound and allylamine and diaminodiphenylmethane as an amine compound, and to a method of preparing the same. The polybenzoxazine precursor may serve to prepare a hardened material having excellent thermal and electrical characteristics and dimensional stability. Accordingly, the polybenzoxazine precursor may be available for use in a copper clad laminate, a semiconductor encapsulant, a printed circuit board, an adhesive, a paint, and a mold.
