| titleOfInvention | A kind of benzoxazine oligomer of maleimide base group end-sealed type and preparation method thereof |
| abstract | The invention belongs to thermosetting resin and its preparation technical fields, provide a kind of benzoxazine oligomer and preparation method thereof of maleimide base group end-sealed type.Preparation method is made of two steps.Step 1: preparing maleimide-functionalised phenol using amino-phenol and maleic anhydride as raw material reaction；Step 2: preparing the benzoxazine oligomer of maleimide base group sealing end with maleimide-functionalised phenol, diamine compounds, diphenols compound and polyformaldehyde reaction.The benzoxazine oligomer of the maleimide base group sealing end of the method preparation, it is characterized in that maleimide base group is introduced into benzoxazine oligomer, the degree of cross linking of benzoxazine resin is further improved, so that the thermal stability of benzoxazine be greatly improved.Meanwhile maleimide base group reduces the rigidity of benzoxazine, keeps machine-shaping more convenient.Entirety preparation process of the present invention is simple, lower to equipment requirement, is suitable for large-scale production. |
