| titleOfInvention | Carboxyl modified polyvinyl alcohol and method for preparing same |
| abstract | Provided is carboxyl modified polyvinyl alcohol, which is prepared with raw materials of a monomer, an initiator and a solvent. The monomer comprises vinyl acetate and a second comonomer, the second comonomer is one solvent or a combination of any solvents selected from maleic acid, itaconic acid, glutaconic acid and itaconic acid anhydride. The preparation method comprises that the continuous polymerization in three kettles is adopted; the vinyl acetate monomer, the second comonomer prepared with the above solvents and the initiator solution are added into three serial polymerization kettles to react; the residence time of the reaction in each polymerization kettle is 60-180 min; and the carboxyl modified polyvinyl alcohol is then prepared through alcoholysis. The method has advantages of high polymerization efficiency, high production efficiency and simple operation. The carboxyl modified polyvinyl alcohol is characterized by excellent cross linking reaction performance, water solubility performance, dispersing performance, rheological performance, anti-skinning performance and anti-foaming performance. |
