摘要

THE INSTANT INVENTION IS A POLYPROPYLENE COMPOSITION, A METHOD OF PRODUCING THE SAME, AND ARTICLES MADE THEREFROM. THE POLYPROPYLENE COMPOSITION ACCORDING TO INSTANT INVENTION INCLUDES THE REACTIVE MELT BLENDING PRODUCT OF A HIGH CRYSTALLINE POLYPROPYLENE HAVING A CRYSTALLINITY OF AT LEAST 64 PERCENT, AN ELASTOMER, A COUPLING AGENT, AND OPTIONALLY A FILLER. THE POLYPROPYLENE COMPOSITION ACCORDING TO INSTANT INVENTION HAS A MELT FLOW RATE IN THE RANGE OF LESS THAN 1 G/10 MINUTES MEASURED AT 230�C UNDER A LOAD OF 2.16 KG IN ACCORDANCE WITH ASTM-D 1238. THE METHOD OF PRODUCING A POLYPROPYLENE COMPOSITION ACCORDING TO INSTANT INVENTION INCLUDES THE FOLLOWING STEPS: (1) REACTIVE MELT BLENDING A HIGH CRYSTALLINE POLYPROPYLENE HAVING A CRYSTALLINITY OF AT LEAST 64 PERCENT, AN ELASTOMER, AND OPTIONALLY A FILLER IN THE PRESENCE OF A COUPLING AGENT; AND (2) THEREBY PRODUCING THE POLYPROPYLENE COMPOSITION HAVING A MELT FLOW RATE IN THE RANGE OF LESS THAN 1 G/10 MINUTES MEASURED AT 230�C UNDER A LOAD OF 2.16 KG IN ACCORDANCE WITH ASTM-D 1238. THE ARTICLES ACCORDING TO INSTANT INVENTION INCLUDE THE INVENTIVE POLYPROPYLENE COMPOSITION INCLUDING THE REACTIVE MELT BLENDING PRODUCT OF A HIGH CRYSTALLINE POLYPROPYLENE HAVING A CRYSTALLINITY OF AT LEAST 64 PERCENT, AN ELASTOMER, A COUPLING AGENT, AND OPTIONALLY A FILLER.
