摘要

ANTI-BLOCKING POLYMER COMPOSITIONS COMPRISE AT LEAST ONE ETHYLENE/A-OLEFIN INTERPOLYMER AND AT LEAST ONE ANTI-BLOCKING AGENT COMPRISING AN AMIDE. THE ETHYLENE/A- OLEFIN INTERPOLYMERS ARE A MULTI-BLOCK COPOLYMER COMPRISING AT LEAST ONE SOFT BLOCK AND AT LEAST ONE HARD BLOCK. THE ANTI-BLOCKING AGENT CAN BE ERUCAMIDE OR OTHER AMIDES. THE ANTI- BLOCKING POLYMER COMPOSITION HAS A PELLET BLOCKING STRENGTH OF EQUAL TO OR LESS THAN 100 LBS/FT2 (4800 PA). WHEN THE ANTI-BLOCKING POLYMER COMPOSITION IS MADE INTO A FILM, THE FILM HAS A BLOCKING FORCE OF LESS THAN ABOUT 100 GRAMS, MEASURED ACCORDING TO ASTM METHOD D-3354.
