Patent number: 9085681Abstract: A low gloss capstock compound is disclosed. The combination of gloss inhibiting agents, metal-based ionomer thermoplastic resins, and acid scavenger added to conventional polyethylene polymer resin achieves a gloss angle at 85° of below 10 GU. Optionally, the compound can also include weathering agents to improve outdoor durability. The compound can be fully formulated or a masterbatch for let-down into polymer to form the fully formulated compound.Type: GrantFiled: February 9, 2012Date of Patent: July 21, 2015Assignee: PolyOne CorporationInventors: Thomas Majewski, Hari Rajaraman, Roman B. Hawrylko

Patent number: 8252855Abstract: A liquid color concentrate is disclosed, having a liquid acrylic-based polymer carrier; colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combinations thereof. The liquid polymer is compatible with a variety of plastic resins, especially optically clear plastic resins, such as polycarbonate, polymethyl methacrylate, and styrene-acrylonitrile.Type: GrantFiled: March 27, 2007Date of Patent: August 28, 2012Assignee: PolyOne CorporationInventors: Hari Rajaraman, Stephen Cranney, Thomas Majewski, Peter Prusak

Patent number: 8168697Abstract: Coated colored biofiber for thermoplastic articles is disclosed. The coating on the biofiber comprises film-forming polymeric binder, surfactant, and colorant. The colorant can be one or more pigments, one or more dyes, or combinations thereof. The coated colored biofiber can be used in thermoplastic compounds to simulate the appearance of natural wood while adding durability.Type: GrantFiled: July 25, 2008Date of Patent: May 1, 2012Assignee: Polyone CorporationInventors: Hari Rajaraman, Stephen J. Cranney, Thomas M. Majewski

Patent number: 7973099Abstract: A pre-processed polymer composite is disclosed comprising a heat-sensitive polymer resin particle; particles of colorant or functional additive in association with the heat-sensitive polymer resin particle; and a thermoplastic encapsulant to form a film around the associated polymer and colorant or functional additive particles. The method of making the polymer composite avoids a melting of the heat-sensitive polymer resin particles, which avoids contributing to heat history of the polymer prior to extrusion or molding into the form of the final plastic article.Type: GrantFiled: October 19, 2007Date of Patent: July 5, 2011Assignee: PolyOne CorporationInventor: Hari Rajaraman
