Barrier polymers having high heat distortion temperatures
Abstract
Abstract POLYMER COMPOSITIONS PREPARED BY THE INTERPOLYMERIZATION OF AN INTIMATE MIXTURE OF ACRYLONITRILE, VINYLIDENE CHLORIDE AND ACRYLATE MONOMERS WHICH ARE USEFUL IN THE FABRICATION OF PACKAGING MATERIALS. THE INTERPOLYMERS OF THIS INVENTION CAN BE READILY FORMED BY SOLVENT CASTING, COMPRESSION MOLDING, CALENDERING, EXTRUSION, AND BLOW MOLDING TECHNIQUES INTO FILMS OR CONTAINERS HAVING OUTSTANDING OXYGEN BARRIER PROPERTIES THEREBY AFFORDING EXCELLENT PROTECTION AGAINST OXYGEN DEGRADATION TO OXYGEN SENSITIVE MATERIAL PACKAGED THEREIN. FILMS AND CONTAINERS PREPARED FROM MANY OF THE PREFERRED INTERPOLYMERS OF THIS INVENTION ALSO HAVE SURPRISINGLY HIGH HEAT DISTORTION TEMPERATURES. THIS UNIQUE COMBINATION OF PROPERTIES MAKES THESE PREFERRED POLYMERIC MATERIALS IDEALLY SUITED FOR THE FABRICATION OF HOT-FILL CONTAINERS USED IN THE PACKAGING OF OXYGEN SENSITIVE FOODSTUFFS, SUCH AS KETCHUP.
