| titleOfInvention | Preparation method of narrow-molecular-weight-distribution vinyl resin and catalyst used by preparation method |
| abstract | The invention discloses a preparation method of a narrow-molecular-weight-distribution vinyl resin and a catalyst used by the preparation method. The preparation method comprises the following steps: a. preparation of transition metal catalyst dissolved solution, namely, carrying out ultrasonic mixing on 10-30 parts by weight of organic transition metal acid salt, 0-20 parts by weight of non-polar solvent and 70-90 parts by weight of polar solvent until the mixed solution is uniform and transparent; and b. preparation of vinyl ester resin, namely, mixing and dissolving an epoxy resin, unsaturated monocarboxylic acid and the catalyst prepared in the step a at 70 DEG C, reacting for 1 hour, heating to 90 DEG C, continuing reacting until the acid number is less than 10, finishing the reaction, adding styrene, stirring uniformly, and cooling to obtain the vinyl ester resin. The technical scheme can quickly prepare the vinyl resin reaction in the epoxy resin/(methyl) acrylic acid system at lower temperature, and can effectively control side reactions. The synthesized resin has the advantages of low viscosity, high glass transition temperature and the like. |
