heat thickening composition for coating baths based on a copolymer possessing a critical temperature of solubility lower

摘要

Heat thickening composition for coating baths comprises at least a heat-sensitive copolymer with a comb structure, consisting of a polymeric 'skeleton' segment, on which are grafted at least two lateral polymeric segments, identical or different, with either the skeleton or lateral segments having a low critical solubility temperature (LCST) = 30-80 deg C. An Independent claim is also included for use of said composition in coating bath for paper or cardboard.
