SURFACE MODIFIED SILICA BY ALKYL SULPHONATED TETRAZOLE COMPOUND, PREPARING METHOD THEREOF, AND RESIN COMPOSITION CONTAINING THE SAME

摘要

This invention relates to a surface modified silica by an alkyl sulfonated tetrazole compound, a preparation method thereof, and a resin composition containing the same. The silica according to this invention can exhibit superior adhesion to a metal. An insulating film or a prepreg for a printed circuit board which is manufactured using the resin composition also have superior adhesion to a metal.
