摘要：
Copolymers based on unsaturated mono- or dicarboxylic acid derivatives, oxyalkylene glycol alkenyl ethers and optionally vinylic polyalkylene glycol or ester compounds are described and also their use as additives for aqueous suspensions based on mineral or bituminous binders, in particular cement, gypsum, lime, anhydrite, or other calcium sulphate-based binders, and based on pulverulent dispersion binders. The copolymers according to the invention impart to the aqueous binder suspensions a very good dispersing and liquefying action with, at the same time, simultaneous excellent processing properties. Moreover, the oxyalkylene glycol alkenyl ethers according to the invention are industrially relatively simple and inexpensive to prepare and need comparatively low initiator concentrations in the copolymerization.
