Abstract
A sulfur-copolymerized chloroprene latex composition containing sulfur-copolymerized chloroprene latex, a nonionic surfactant and a monobasic acid, in which the monobasic acid has a pKa of 4.0 to 6.0, a method for producing the same, and a modified asphalt emulsion composition.
Claims14
A method for producing a sulfur-copolymerized chloroprene latex composition, comprising:
- a polymerization step of polymerizing a chloroprene monomer and sulfur to obtain sulfur-copolymerized chloroprene latex;
- and
- a mixing step of mixing the sulfur-copolymerized chloroprene latex and a monobasic acid having a pKa of 4.0 to 6.0,
- wherein, in at least one step of the polymerization step and the mixing step, the sulfur-copolymerized chloroprene latex and a nonionic surfactant are mixed together.
