Hydroxy polyalkylene glycol function (meth)acrylic comb polymers, their use as shear-thinning agents in coating dispersionsand dispersions containing them

摘要

The present invention is based on comb polymers featuring a (meth) acrylic skeleton with side chains of the hydroxy or alkoxy polyalkylene glycol type, and which enter into the composition of paper coating dispersions. Among other things, it offers an improvement based on the particular choice of a hydroxy group at the end of the side chain.
