Abstract

Composite films have been obtained from mixtures of hydroxyethyl cellulose and hydroxypropyl cellulose aqueous solutions with poly-N-methyl-N-vinylacetamide. The structural organization of composite films has been studied by dynamic mechanical analysis and X-ray diffraction analysis, and the composition ranges where cellulose ethers are compatible with synthetic polyamide and form mixed structural formations have been determined. The values of the solubility parameter and the surface energy of polymers have been compared with their compatibility in the solid state.
