METHOD FOR MAKING COMB POLYMERS BY DRYING THEN FUNCTIONALIZATION OF THE METH(ACRYLIC)POLYMER BACKBONE, RESULTING POLYMERS AND USES THEREOF |
摘要 |
The present invention relates to processes for manufacturing comb polymers having a principal (meth)acrylic chain and polyoxyalkylated lateral groupings, obtained by drying of a solution containing at least one homopolymer of (meth)acrylic acid and/or at least one copolymer of (meth)acrylic acid with at least one other monomer, followed by functionalisation of the intermediate dry product by esterification with at least one alkoxy polyoxyalkylene glycol, and/or amidification with at least one alkoxy polyoxyalkylene amine, or ethoxylation with at least one alkylene oxide. |
