Abstract:
A kind of waterborne branched super-dispersant was synthesized by copolymerization of methacrylate polyglocol monoester and( methy I)acrylic acid. Compared with the traditional polymer dispersant， this super-dispersant shows better dispersing capability and stabilization for pigments and is a novel kind of highly efficient dispersant.
Key words:
