EMULSION POLYMERIZATION METHOD USING REACTIVE EMULSIFYING AGENT, AQUEOUS POLYMER DISPERSION OBTAINED BY SAME, AND POLYMER FILM |
摘要 |
Provided is an emulsion polymerization method for carrying out emulsion polymerization of monomers using a reactive emulsifier in an aqueous medium in the presence of a polymerization initiator, the emulsion polymerization method being capable of solving problems such as an enhancement of a rate of copolymerization of the reactive emulsifier with the monomer, dissolution of a bubbling trouble, a more improvement of water resistance of a coating film, etc. The emulsion polymerization is carried out using one or two or more kinds of polymerizable unsaturated monomers X having at least one carbon-carbon double bond in a molecule, one or two or more kinds of reactive emulsifiers Y having at least one polymerizable group in a molecule, and one or two or more kinds of polyfunctional monomers Z1 having two or more polymerizable unsaturated groups in a molecule and having a molecular weight per functional group of less than 150, or one or two or more kinds of hydrophilic monomers Z2 having one polymerizable unsaturated group and a hydrophilic group in a molecule and having an average molecular weight of less than 250, with a proportion of the total use amount of the polyfunctional monomer Z1 or hydrophilic monomer Z2 to the total use amount of the reactive emulsifier Y being in the range of Z1/Y = 1/3 to 1/30 or Z2/Y = 1/1 to 1/30 in terms of a mass ratio. |
