  • Patent number: 12134213
    Abstract: The present disclosure provides a process. The process includes providing a blend containing (A) a first powder including (i) a polyolefin having a density from 0.860 g/cc to 0.910 g/cc, and a melt index from 1.5 g/10 min to 1,000 g/10 min; (ii) from 1 wt % to 15 wt % of a dispersant selected from an acrylic dispersant, a poloxamer, and combinations thereof; and (iii) optionally, a polyolefin wax, the first powder having a mean volume average particle size from 1 ?m to 300 ?m; and (B) a second powder including an ethylene/?-olefin copolymer having (i) a density from 0.920 g/cc to 0.955 g/cc; and (ii) a melt index from 1.0 g/10 min to 15 g/10 min, the second powder having a mean volume average particle size from 325 ?m to 4,000 ?m; and rotational molding the blend to form a rotational molded article.

  • Publication number: 20230407067
    Abstract: A polyethylene composition comprising suitable for use in injection molding, the polyethylene composition comprising: from 2 wt. % to 25 wt. % of a high molecular weight component consisting of an ethylene/alpha-olefin copolymer, wherein the high molecular weight component has a density of from 0.910 g/cc to 0.971 g/cc, a melt index (12.16) of greater than 0.5 g/10 min to less than 1.5 g/10 min, a molecular weight distribution (Mw/Mn) of 6.0 to 20.0; from 75 wt. % to 98 wt. % a low molecular weight component consisting of an ethylene homopolymer or an ethylene/alpha-olefin copolymer, wherein the ethylene homopolymer or an and a molecular weight distribution (Mw/Mn) of less than 6.0; wherein the polyethylene composition has a shrinkage anisotropy that is less than the shrinkage anisotropy of the low molecular weight component.
