COPOLYMER LATEX AND METHOD FOR PRODUCING THE SAME |
摘要 |
Disclosed is a copolymer latex obtained by emulsion polymerization of a monomer mixture containing (a) 30-70% by mass of a conjugated diene monomer, (b) 0.1-15% by mass of an ethylenically unsaturated carboxylic acid monomer and (c) 15-69.9% by mass of one or more other copolymerizable monomers. The copolymer latex is characterized in that the toluene in-soluble content in the dried product obtained by drying the copolymer latex is 95-100% by mass; the mass ratio of the toluene-swollen toluene insoluble content to the dried toluene insoluble content (the toluene swelling degree) is 3.0-6.5; the number average particle diameter of the copolymer latex is 180-400 nm; and the glass transition starting temperature of the dried copolymer latex is within the range from -70°C to -20°C and the glass transition ending temperature thereof is within the range from 10°C to 100°C in differential scanning calorimetry.
