Abstract: A chloroprene rubber having a shade of white only slightly tinged with pale yellow and exhibiting good tackiness is prepared by an aqueous radical emulsion polymerization of chloroprene or a mixture comprised of chloroprene and a copolymerizable monomer, wherein the polymerization is effected by using an alkali metal salt of a disproportioned rosin acid as an emulsifier, and a water-soluble polymeric substance as a dispersion stabilizer which has a sulfonic acid group and/or sulfate ester groups, which group has been introduced by an addition polymerization procedure or by a procedure of a polymeric reaction following an addition polymerization.

Abstract: PROBLEM TO BE SOLVED: To provide chloroprene latex which maintains stability while stored, and can be used over a long period of time; and to provide an adhesive composition containing the same.
SOLUTION: The chloroprene latex is characterized in that the particle diameter (median diameter) D50 (μm) of the latex is in a range represented by formula (1): 0.037×lnT(°C)≤D50(μm)≤0.2, (wherein, lnT (°C) represents natural logarithm of the polymerization temperature (°C)), and the weight ratio E(%) of an emulsifier contained in the latex is in a range represented by formula (2): -10×D50(μm)+3≤E(%)≤-15×D50(μm)+6. The adhesive composition contains the chloroprene latex.

Abstract: PROBLEM TO BE SOLVED: To provide a primer for polychloroprene rubber latex adhesive and an adhesion method using the same, which enable strong adhesion between foamed bodies to be used as materials for sports goods and wet suits or between a foamed body and a textile, while conventional polychloroprene rubber latex adhesives do not give sufficiently strong adhesion of various foamed bodies.
SOLUTION: The adhesion method comprises the steps of: coating each surface of a foamed body first with a primer for adhesion containing a polyisocyanate compound and then with an adhesive containing polychloroprene latex as a main component; and successively bringing one of the coated surfaces come into contact with the other surface to be adhered.

Abstract: PURPOSE:To obtain a latex for adhesive comprising a mixture of plural latexes containing specific copolymers having different molecular weight and excellent in ordinary-temperature and high-temperature adhesive force, softening temperature, water resistance and latex stability. CONSTITUTION:This latex for adhesive is a copolymer of a chloroprene monomer and a carboxyl group-containing vinyl monomer and is composed of a mixture of latexes of (A) a copolymer having 200000-500000 weight-average molecular weight of a part soluble in an organic solvent with (B) a copolymer having 500000-800000 weight-average molecular weight of a part soluble in an organic solvent [preferably in (90/10) to (10/90) dried weight ratio of components A/B]. Furthermore, the cloroprene-based adhesive is obtained by blending 10-60 pts.wt. of a tackiness-providing agent such as a phenolic resin with 1-5 pts.wt. of a metal oxide or a metal hydroxide.
