    Abstract: Processing parameters of polypropylene and/or polyethylene are adjusted by combining them with a non-fluorinated process aid. The process aid is an oleochemical derivative and/or a wax having a viscosity of from 10 cP to 100 cP. The wax is a branched ethylene-propylene copolymer. The processing parameter, e.g., pressure at the die, or volumetric output is adjusted for the polypropylene and/or polyethylene compared to the polypropylene and/or polyethylene without the non-fluorinated process aid at the same processing conditions. The mechanical properties of an extruded polymeric article including the non-fluorinated process aid are the same or are improved compared to the same composition without the non-fluorinated polymer processing aid or one that includes a fluorinated processing aid.

    Abstract: Disclosed is an injection stretch blow molded (ISBM) container containing a surface having a static coefficient of friction (COF) of 0.15 to 0.21, a dynamic COF of 0.06 to 0.1, wherein the surface retains a water contact angle of 76° or higher for up to three minutes after wetting of the surface with a water drop of 14 to 16 mm diameter and the container is made with a polymeric composition containing a high density polyethylene (HDPE) having a dispersity (Mw/Mn) of 9 or higher as measured by GPC; a MI2 of 1 g/10 min or higher as measured by ASTM D-1238; 190° C./2.16 kg, as measured by ASTM D-1238; and an environmental stress crack resistance (ESCR) at 100% Igepal of >150 hours as measured by ASTM D-1693, B.

    Abstract: A high melt strength polypropylene is formed using maleated polypropylene and a combination of coupling agents and acid neutralizers. The maleated polypropylene can be formed using multi-functional monomers. The high melt strength polypropylene can be useful for foaming, sheet extrusion thermoforming, extrusion blow molding, extrusion coating, fiber, film, and the like.
