Title:
PROCESS FOR PRODUCING ENLARGED LATEX
Document Type and Number:
WIPO Patent Application WO/2001/046267
Kind Code:
A1
Abstract:
A process for producing a particle-enlarged latex, characterized by (1) causing (a) an anionic surfactant and (b) at least one surfactant selected from the group consisting of cationic surfactants and amphoteric surfactants to be present in a latex, (2) adding as a coagulant/enlarging agent at least one member selected from the group consisting of (i) an inorganic acid, (ii) an organic acid, (iii) a substance which yields an acid in water, (iv) a combination of two or more substances which react with each other to yield an acid, and (v) a substance which yields an acid upon irradiation with actinic rays to the latex in the presence of these surfactants, and (3) causing the acid attributable to the coagulant/enlarging agent to act on the latex to thereby increase the diameter of the particles in the latex; the particle-enlarged latex obtained; a graft copolymer obtained by polymerizing a polymerizable monomer with the particle-enlarged latex; and a resin composition comprising the graft copolymer and a thermoplastic resin.
