| titleOfInvention | The dicarboxylic acid monomer and its polyester copolymer of a kind of ketone groups containing benzoxazine |
| abstract | The present invention relates to the dicarboxylic acid monomer and its polyester copolymer of a kind of ketone groups containing benzoxazine, the dicarboxylic acid monomers of the ketone groups containing benzoxazine is with paraphthaloyl chloride or naphthalene dimethyl chloride to be obtained by the reaction by 2 amino terephthalic acid (TPA)s；Polyester copolymer be with terephthalic acid (TPA) or or the dicarboxylic acid monomer of dimethyl terephthalate (DMT), ethylene glycol and the ketone groups containing benzoxazine carry out polycondensation and form, the molar ratio of three classes monomer is 100:(10~90):(1~99).The advantage of the invention is that：On the polyester backbone that the dicarboxylic acid monomer of the ketone groups containing benzoxazine is connected to by the method for copolymerization, assign the good ultraviolet light stability of polyester, the mechanical property for keeping polyester excellent simultaneously overcomes polyester of the prior art and adds larger content (weight ratio>5%) after UV absorbers the shortcomings that mechanical properties decrease. |
