Abstract

Unsaturated polyesters of defined composition with a low content of polyalkylene glycol radicals in a narrow molecular weight range can be dispersed in water without external emulsifiers. These dispersions produce, after hardening, water and chemical resistant coatings with good mechanical properties.
