Continuous production of reduced gel content hydroxylated addition polymers

One or mixture of claimed and is formed from at least one r9 is monoethylenically unsaturated monomer is acrylic acid 2 ' - ethyl ester, about 0 to about α weight, β the unsaturated carboxylic acid to the acrylic acid or methacrylic acid and remainder method of the monomer continuously producing radical said polymer, wherein the monomers of the remainder is the free group is copolymerized compound to the styrene, methyl methacrylate and butyl acrylate. The radical polymerization is in a solvent or more of solvent, and surpassing under normal pressure the pressure is conducted at about 150℃- about 310℃ temperature. The resolvers' and hydrogen parameter's chain of the solvent or the volume average value of the complete solvent mixture of of the value and polar apportioning it comprises one of root-mean-square value of about 6 to about 15 to about. The complete or solvent, wherein a method for polymerization under the condition having a volatile, is located at the condensed liquid phase of the mixture of the monomer and solvent in the reaction mixture of conversion device the inner surface is formed comprises at least 50mol% solvent, to reduce the inner surface of the formation of gel. The method for continuous production of a polymer quite the long time, and reducing the gel particles and formation of gel thereof.
