Disclosed herein is a polymer composition for hydrophilic treatment containing a volatile base andn In a) an olefinic polymer with more than 50% carboxylic groups, b) a polymer free of carboxylic groups containing groups capable of forming hydrogen bonds, and eventually c) a polymer containing carboxylic groups and hydrogen-bond-forming groups: or IIn a polymer with more than 50% carboxylic groups and up to 50% hydrogen-bond-forming groups. n Also mentioned are mixing processes for obtaining these compositions, a polymerization method for obtaining composition II, and a coating method for preparing a hydrophilic polymer coating having water insolubility. |
