Patent number: 8168710Abstract: A golf ball having a core, a cover layer, and an optional intermediate layer disposed between the core and the cover layer is disclosed and described. One or more of the core, the cover layer, or the intermediate layer is formed of a highly neutralized polymer blend of an acid copolymer and a metallocene-catalyzed copolymer, an olefinic block copolymer, a sufficient amount of a suitable cation source and a fatty acid or salt of a fatty acid. The highly neutralized polymer blend is neutralized from 80% to 100% while still retaining processability. Further, the core can have a diameter of 0.5 inches to about 1.62 inches and an Atti compression less than or equal to 105. The cover layer can have a material hardness between about 30 and 70 Shore D.Type: GrantFiled: June 1, 2009Date of Patent: May 1, 2012Assignee: Acushnet CompanyInventors: Murali Rajagopalan, Michael J.

Publication number: 20120010365Abstract: A method of making resin composition having excellent wear properties that includes 50 to 99 wt. % of a polycarbonate resin and from 1 to 50 wt. % of a polyolefin that has been modified with at least one functional group selected from a carboxyl, an acid anhydride, an epoxy groups or mixtures containing at least one of the foregoing functional groups, each based on the total combined weight of the resin composition, exclusive of any filler. The resin composition optionally contains an unmodified polyolefin and/or a bi-functional monomer. The resin composition can be molded into articles having improved wear characteristics. The process is a one-step process that improves the efficiency and/or yield of the resin composition as compared to prior-art two-step processes.Type: ApplicationFiled: September 20, 2011Publication date: January 12, 2012Applicant: SABIC INNOVATIVE PLASTICS IP B.V.Inventors: Ye-Gang Lin, Donghai Sun, David Xiangping Zou

Publication number: 20110256403Abstract: A process for forming a nanoparticle composition is provided. The process includes polymerizing conjugated diene monomer in a hydrocarbon solvent to form a first reaction mixture, and charging excess alkenylbenzense monomer and anionic catalyst to form mono-block and diblock polymers. Micelles of said mono-block and diblock polymers are formed, and at least one crosslinking agent is added to cross-link the micelles and form nanoparticles. The nanoparticles preferably have a poly(alkenylbenzene) core and an outer layer including monomer units selected from the group consisting of conjugated dienes, alkenylbenzenes, alkylenes, and mixtures thereof, and a size distribution of between about 1 and 1000 nm.Type: ApplicationFiled: March 2, 2004Publication date: October 20, 2011Inventors: Xiaorong Wang, Victor J.
