    摘要: The present invention relates to a water-based polymer composition, comprising: at least one polymer (P) comprising recurring units (R1), from 0 to at most 25% mol of said recurring units (R1) comprising a carboxylic acid group (in acid or salt form); at least one aromatic polyamic acid (A) comprising recurring units, more than 50% mol of said recurring units comprising at least one aromatic ring and at least one amic acid group and/or imide group [recurring units (R2)], more than 50% mol of recurring units (R2) comprising at least one amic acid group, part or all of the amic acid groups being neutralized by at least one basic compound (B); water; optionally, at least one organic solvent (S) of the aromatic polyamic acid (A), in an amount of less than 20% wt with respect to the weight of the aromatic polyamic acid. The polymer (P) is preferably a fluoropolymer; it can be either a partially fluorinated fluoropolymer, such as ECTFE, or a perfluorinated fluoropolymer such as TFE polymers.The water-based polymer compositions of this invention may be notably found useful for coating applications where organic solvents may not be desired or tolerated.
