Method for producing water soluble polymers of esters from ethylenically unsaturated carboxylic acids and polyalkylene glycols |
| abstract |
The invention relates to a method for producing water soluble polymers of esters from ethylenically unsaturated carboxylic acids and polyalkylene glycols by azeotropic esterification of ethylenically unsaturated carboxylic acids with polyalkylenglycols which are closed at one side by end groups. Esterification is performed in the presence of organic solvents which together with water form an azeotrope of at least 85 weight %. Subsequent radical polymerization is performed on the esters thus obtained thereby optionally together with other ethylenically unsaturated monomers in an aqueous medium. The organic solvent is azeotropically strip distilled out of the reaction mixture during the polymerization process and strip distilled water is reintroduced or the amount of water strip distilled out of the reaction mixture is replaced by adding fresh water. |
