Abstract: PURPOSE: A method for preparing an acryl-based polymer nano water dispersion is provided, to improve the environmental-friendliness of the acryl-based polymer nano water dispersion used in polymer cement and the tensile strength of the polymer cement. CONSTITUTION: The method comprises the steps of stirring the mixture comprising 45-55 parts by weight of an acryl-based monomer, 0.8-1.2 parts by weight of polyoxyethylene lauryl ether represented by C12H25O(C2H4O)nH (wherein n is 21-50) as a nonionic surfactant and 25-35 parts by weight distilled water at a temperature of 40-70 deg.C to prepare a stable monomer emulsion; stirring the mixture comprising 35-45 parts by weight of distilled water and 0.04-0.06 parts by weight of an anionic surfactant at a temperature of 60-80 deg.C and adding 0.2-1.5 parts by weight of an initiator to prepare an aqueous solution mixture; and continuously dropping the monomer emulsion to the aqueous solution mixture to perform the emulsion polymerization. The obtained acryl-based polymer nano water dispersion has a particle size of 315-350 nm and a polymer solid content of 37-41 wt%.

Abstract: PURPOSE: A method for preparing the graft polymer of a polyvinylidene fluoride resin and an acryl derivative and its polymerization apparatus are provided to use little solvent, to reduce the reaction time, to improve the graft rate and to modify the surface of the polymer. CONSTITUTION: The method comprises the steps of putting a solid polyvinylidene fluoride resin supplying the main chain of a linear polymer into a solid state polymerization reactor; purging nitrogen gas to remove the oxygen present in the reactor; heating the temperature to 90-120 deg.C; injecting a solid state initiator to generate radicals at the polymerization reaction temperature; spraying a liquid acryl derivative in the state of aerosol; and reacting it at the polymerization reaction temperature for 10-50 min after the injection of an initiator. Preferably the initiator is benzoyl peroxide, and the acryl derivative is selected from the group consisting of acrylic acid, methacrylic acid and glycidyl methacrylate.
