Abstract: AN IMPROVED METHOD FOR UNIFORMLY MIXING POLYMER MATERIALS AND ADDITIVES WHEREIN ONE CONSTITUENT MAY BE A LOW VISCOSITY COMPONENT AND THE OTHER A VISCOUS POLYMER MIXED BY PASSAGE THROUGH AN EXTRUDER HAVING THE OVERALL LENGTH COMPRISED OF A FEED ZONE 10-20 PERCENT; A TRANSISTION ZONE 27-40 PERCENT AND A METERING ZONE OF 45-60 PERCENT. WITHIN SAID METERING ZONE THERE ARE 2-6 FLIGHT INTERRUPTIONS, SAID METHOD OF MIXING POLYMERS PRODUCING AN EXTRUDATE WITH A COEFFICIENT OF PARTICLE VARIATION OF LESS THAN 30 PERCENT AND SAID POLYBLENDS AND LOW VISCOSITY MATERIALS INCORPORATED IN POLYMERS BEING BOTH

SUITABLE FOR PIECE DYEING WHEN CONVERTED INTO TEXTILE ARTICLES.
