Research on Preparation of Transparent Hydrophilic Antifogging Acrylate Resin

摘要

Solution polymerization method was used to prepare hydrophilic antifogging acrylate resin. By means of comparison, the optimum synthesis technology conditions was obtained that ethyl acrylate was used as soft monomer , methylcrylate was used as hard monomer. The best functional monomers was acrylic acid and methyl acrylic acid. The accessory functional monoer was P-hydroxyl ethyl acrylate. Cross-linking agent methylol acrylamide belongs to self-cross-linking system. Crosslinker was N-hydroxymethyl acrylamide.The quality rate of cross-linking agent and carboxylic acid is 4 to 1 .The resin can be cured perfectly at the temperature of 100℃ in 40 min. The prepared acrylate resin had excellent water-solubility and antifogging.
