Abstract:
A process for manufacturing an acrylic antislipping agent comprising the steps of:a) emulsion polymerizing acrylic monomers to obtain a first acrylic latex having a glass transition temperature (Tg) of greater than or equal to 90.degree. C., wherein, the dried homopolymer of said acrylic monomers have glass transition temperatures ranging from 8 to 153.degree. C.;b) emulsion polymerizing of acrylic monomers to obtain a second acrylic latex having a Tg less than or equal to -5.degree. C., wherein, the dried homopolymers of said acrylic monomers have glass transition temperatures ranging from -85 to -5.degree. C.;c) adding at least one acrylic monomer containing at least one carboxyl acid group to said first acrylic latex;d) adding at least one acrylic monomer containing at least one carboxyl acid group to said second acrylic latex; ande) blending said first and said second acrylic latexes together through neutralization with aqueous ammonia to form a final acrylic latex.
