The invention discloses a fluoroalkyl (alk)acrylate polymer containing terminal alkyl ester or carboxylic acid, a preparation method and application thereof. The polymer has a structure shown in formula (I), and its preparation steps include: 1 to 20 parts of alkyl malonate salt initiator, 40 to 200 parts of organic solvent, 100 parts of (alk)acrylic acid fluorothane Mix base ester monomers and react for 0.2 to 20 hours to obtain fluoroalkyl (alk)acrylate polymers containing terminal alkyl esters; mix 1-5 parts of fluoroalkyl (alk)acrylate The ester polymer is hydrolyzed in 22-110 parts of the mixed hydrolyzate to prepare the fluoroalkyl (alk)acrylate polymer. The polymer of the present invention contains terminal alkyl esters or terminal carboxyl groups, and has good amphiphilicity and strong stain resistance; the present invention adopts a non-metallic carbanion polymerization method with mild polymerization conditions, high monomer conversion rate (≥96%), and no Initiator residues, resulting products with narrow molecular weight distribution and controllable "activity" characteristics. |
