Process for producing copolymer latex and paper coating composition, carpet backing composition or adhesive composition comprising said latex

摘要

A process is provided for producing a copolymer latex having a gel content of 10-98% by weight, involving emulsion polymerizing: (a) 20-65% by weight of a conjugated diene compound; (b) 0.1-10% by weight of a combination of an ethylenically unsaturated monocarboxylic acid with an ethylenically unsaturated dicarboxylic acid; and (c) 33-79.5% by weight of at least one ethylenically unsaturated compound other than the components (a) and (b), in the presence of (d) 0.1 to 10 parts by weight of an alpha -methylstyrene dimer, per 100 parts by weight of a total of components (a), (b) and (c).
