METHOD FOR IMPROVING PROCESSABILITY OF POLYETHYLENE BLEND |
摘要 |
A method for improving the processing characteristics of a polyethylene blend comprised of at least two polyethylene components having at least one dissimilar rheological property. The method comprises the steps of (a) establishing a functional relationship between free radical generator dosage and a rheological property for at least one polyethylene component of the polyethylene blend; (b) determining a free radical generator dosage from said relationship for use with at least one polyethylene component, said dosage level sufficient to enable the polyethylene component so treated to exhibit a rheological property substantially similar to that of all components present in the blend; (c) treating at least one polyethylene component at the dosage of free radical generator determined in step (b); and (d) blending the polyethylene components in melt form. A process for the extrusion of films from blends of polyethylenes is also provided. |
