[A method for testing the resistance of film-forming polymers against gastric juices (author's transl)]

The authors describe a simple method for preparing and testing isolated polymer-based films, and demonstrate their use by the example of selected polymethacrylate films, mainly containing different concentrations of various plastizisers. The results obtained show that the characterization of film properties by this method may be used for the comparison of filmogenic formulae in the forefield of coating and for prognosticating the film quality to be expected.
