METHOD OF FILTRY EXTRUSION AND SPRAY OR BLASTING OF A MIXTURE CONTAINING A ZIEGLER-NATTA-CATALYZE POLYOLEIN RESIN AND MIXING FOR THE PRACTICE

摘要

A non-volatile, acid acceptor which is soluble in polyolefins is added to a film grade polyolefin resin composition to prevent gel streaking/pinstriping or corrosion during film extrusion processes. The acid acceptor has a molecular weight greater than 180 with less than 5% by weight volatiles at 180 DEG C as measured by a thermal evolution analysis.
