POLY (VINYL-ACETALS) WITH AN IMPROVED BEHAVIOR OF THE VISCOSITY OF MOLTEN MASSES, PROCEDURE FOR ITS PREPARATION AND USE.

摘要

PRODUCTION OF SOLUBLE POLYVINYLACETALS, LOW RETICULATES WITH AN IMPROVED FUSION VISCOSITY BEHAVIOR THROUGH ACETALIZATION OF SOLUBLE POLYVINYLALCOHOLES, WHICH HAVE BEEN MADE BY SOUTHEAST, SOUTHEAST, SOUTHEAST, AND SOUTHEAST ALCOHOLISIS OF SEVILY-SAVED, SOUTH-EYE, AROUND GLIOXALBISACRILAMIDA. WHEN COMPARED WITH COMPARABLE NON-RETICULATED SOLUBLE POLYVINYLACETALS, THE LOW-CROSSLINED POLYVINYLACETALS OF THE INVENTION PRESENT A SUPERIOR STRUCTURAL VISCOSITY AND SHOW SOME SURPRISING PROPERTIES, EXPENSIVE IN THERMOPLASTIC DEFORMATION, ESPECIALLY IN THE FORM OF PLASTIC DEFORMATION. LOW-CROSS-LINKED POLYVINYLACETALS ALSO HAVE IMPROVED MECHANICAL PROPERTIES, COMPARED TO UNLINKED-LINKED POLYVINYLACETALS, AND ARE SUITABLE IN PLASTIFIED LAMINAR FORMULARLY THE PRODUCTION OF COMPOSITE CRYSTALS.
