METHOD OF LATEX PREPARATION CATIONICOS FROM LATEX ANIONICOS

NOVELTY – The preparation of cationic latexes from anionic latexes has introduction of e.g. Al3+, Fe3+ and Cr3+ cations into dispersions of conventional anionic latexes stabilized by high-HLB non-ionic surfactants. The anionic latexes can be polymerized by the addition of the high-HLB non-ionic surfactants. USE – In physical chemistry.

Main Application Field
