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.

Abstract: Disclosed is a rubber composition containing main-chain benzoxazine, in which benzoxazine generates no harmful materials during vulcanization and can thus be used in lieu of a phenol novolac resin used as a resin component of a conventional rubber composition, and also in which the use of benzoxazine, especially main-chain benzoxazine having a high molecular weight, is capable of maintaining excellent mechanical properties and exhibiting high flexibility. The rubber composition of the invention can be utilized for a rubber product, especially a tire product.
