2.2.5Maleic anhydride copolymers

Оглавление

These copolymers contain maleic anhydride instead of acrylic acid. The copolymers are mostly comb-like structures. Ethoxylate chains are also used here to sterically stabilise the pigments. Maleic anhydride chemistry does not allow the broad variety of structures available with acrylates but nevertheless enables development of additives for all kinds of pigments. These additives are very resistant to water.
