Patent number: 11905347Abstract: Propylene and alpha olefin random copolymers are disclosed that have excellent flow characteristics. For instance, the copolymers can be formulated so as to have a melt flow rate of greater than about 45 g/10 min. While still retaining the above flow characteristics, the copolymer can also be formulated to have greater stiffness, low xylene soluble content, and excellent transparency characteristics especially when combined with one or more clarifying agents.Type: GrantFiled: June 7, 2019Date of Patent: February 20, 2024Assignee: W.R. GRACE & CO .- CONN.Inventors: Matthew John Fedec, Jan Willem Van Egmond, John Kalevi Kaarto, Amaia Montoya-Goni

Publication number: 20220177682Abstract: Polypropylene polymer compositions are disclosed that have excellent stiffness properties. The polypropylene polymer compositions are made by combining a first polypropylene polymer with a second polypropylene polymer. The combination of polymers has been found to produce a composition having high stiffness properties in addition to excellent toughness properties. In addition, the polymer composition has good flow properties for being molded into various products and articles. Of particular advantage, the different polypropylene polymers can be produced at relatively high catalyst activity, especially in comparison to high crystalline polymers made in the past.Type: ApplicationFiled: April 3, 2020Publication date: June 9, 2022Inventors: John KAARTO, Jing ZHONG, Amaia MONTOYA-GONI

Publication number: 20220169843Abstract: Polypropylene polymer compositions are disclosed that can be formulated to have excellent clarity properties in conjunction with excellent impact resistance properties at subzero temperatures. The polypropylene polymer compositions are heterophasic compositions containing a first phase polymer combined with a second phase polymer. The first phase polymer is a polypropylene and alpha-olefin copolymer while the second phase polymer is also a polypropylene and alpha-olefin random copolymer. The second phase polymer contains relatively high amounts of ethylene. The increased amounts of ethylene in the second phase polymer were found to dramatically improve impact resistance at subzero temperatures.Type: ApplicationFiled: April 3, 2020Publication date: June 2, 2022Inventors: John Kalevi KAARTO, Jing ZHONG, Amaia MONTOYA-GONI

Patent number: 8048960Abstract: The present invention is a rubber modified monovinylidene aromatic polymer composition where the rubber is a sulfanylsilane chain end modified elastomeric polymer. In the present invention the functionalized rubber provides sufficient grafting levels in standard graft polymerization process technologies to prepare desired rubber particle size distributions and morphologies. Across a range of rubber modified monovinylidene aromatic polymers, it has been found that the use of the modified elastomeric polymers according to the present invention can improve the combinations of resin properties, particularly clarity, surface and physical properties, including both rubber modified monovinylidene aromatic homopolymers (e.g., high impact polystyrene and copolymers (e.g., ABS). The functionalized rubbers have sulfanyl functional groups that provide an optimized reactive grafting site.Type: GrantFiled: March 27, 2008Date of Patent: November 1, 2011Assignee: Styron Europe GmbHInventors: Amaia Montoya-Goni, Jose M.

Publication number: 20100298486Abstract: Monovinylidene aromatic polymers, e.g., general purpose polystyrene or high impact polystyrene, are plasticized with a nonfunctionalized, nonmineral oil, e.g., a vegetable oil such as canola oil, cottonseed oil or the like. The mixture of monovinylidene aromatic polymer and oil is typically and preferably free of any significant amount of functionalized nonmineral oil, and it typically contains at least 0.1 weight percent of the nonfunctionalized, nonmineral oil, alone or in combination with a mineral oil, based on the weight of the polymer. The nonmineral oil has an iodine value of less than 120, and a hydroxyl number of less than 20.Type: ApplicationFiled: September 11, 2007Publication date: November 25, 2010Applicant: DOW GLOBAL TECHNOLOGIES INC.Inventors: Zenon Lysenko, Amaia Montoya-Goni, David Schrader, Alan K.
