Preparation method of polycarboxyl metal phthalocyanine-aromatic copolyester

Abstract

The invention relates to a preparation method of aromatic thermosetting resin containing polycarboxyl metal phthalocyanine. The method includes: employing a phthalic anhydride method to prepare polycarboxyl metal phthalocyanine, adding the metal phthalocyanine into an aromatic thermosetting resin prepolymer monomer and mixing them uniformly, leaving the mixture to undergo a high temperature reaction so as to obtain two prepolymers, i.e. Cx-MPc-COOH and Ax-MPc-COOH, mixing the two prepolymers uniformly, performing high temperature curing, thus obtaining an aromatic thermosetting resin composite material containing polycarboxyl metal phthalocyanine. The various monomers for synthesizing the aromatic thermosetting resin are terminated by carboxyl and ester groups, the polycarboxyl metal phthalocyanine can undergo chain transfer reaction with the monomers so as to be introduced into a molecular network structure of aromatic thermosetting resin. The method makes use of the excellent electron donating ability of metal phthalocyanine to perform coupling with the conjugated structure of aromatic thermosetting resin, thus reaching the purpose of improving dielectric properties of aromatic thermosetting resin. With the properties of high temperature resistance, ablation resistance, easy adhesion and the like, the aromatic thermosetting resin prepared by the invention has important applications in micro-electronics, semiconductors, electromagnetic materials, electrical smart materials and other fields.
