Abstract:
1. A water-based polymer composition, comprising: particles of at least one halogenated polymer (P) in an amount of from 5 to 50% by weight based on the total weight of the composition, wherein the halogenated polymer (P) is a fluoropolymer consisting of recurring units derived from a fluorinated monomer and at least one hydrogenated comonomer; at least one aromatic polyamic acid (A) comprising recurring units (R2), wherein more than 50% mol of said recurring units (R2) comprise at least one aromatic ring and at least one of an amic acid group and an imide group, further wherein: water; and optionally, at least one organic solvent (S) wherein the total amount of the organic solvent is less than 20% by weight with respect to the weight of the aromatic polyamic acid.
