SYNTHESIS OF ACRYLIC WARP SIZE COPOLYMERS WITH STEARYL METHACRYLATE(SMA)BY MINIEMULSION POLYMERIZATION

摘要

The present invention relates to a method for synthesizing a stearyl methacrylate (SMA) copolymer type anti-corrosion agent using a miniemulsion polymerization method, and more specifically, the theoretical glass transition using the Fox equation (1). Adjusting the composition of the monomer such that the temperature (T _g ) is maintained at 10-40 ° C .;;Mixing the monomer in a homogenizer with distilled water in a 1: 1 ratio and making a monomer emulsion through homogenization at room temperature for 10 to 30 minutes at 15,000 to 16,000 rpm;;The polymerization reaction was carried out by injecting a certain amount of monomer emulsion for 1 to 2 hours into the polymerization apparatus in which ammonium peroxide sulfate (APS), an initiator, was dissolved in an aqueous solution, and polymerization was further performed for 1 hour 30 minutes to 3 hours. After the polymerization reaction is completed, the temperature is lowered to room temperature, and then neutralized using an aqueous ammonia solution for 10 to 40 minutes to maintain a neutral pH, and 20% to 25% Brix (%) and solids with methanol (MeOH). The present invention relates to a method for synthesizing a stearyl methacrylate copolymer-type derivatizing agent using a miniemulsion polymerization method and its application.;Miniemulsion, stearyl methacrylate (SMA), homogenization
