| 20120058288 | POLYETHYLENE BASED RESIN, PRODUCING CATALYST FOR THE SAME, METHOD FOR PRODUCING THE SAME, HOLLOW PLASTIC MOLDED ARTICLE CONTAINING POLYETHYLENE BASED RESIN, AND USE OF THE SAME - A polyethylene based resin exhibiting excellent moldability and durability and having an excellent balance between impact resistance and stiffness; and a hollow plastic molded article using the foregoing resin, which exhibits excellent moldability, durability and barrier properties and has an excellent balance between impact resistance and stiffness, are provided. The polyethylene based resin satisfies the following requirements (1) to (4): (1) a high-load melt flow rate (HLMFR) is from 1 to 100 g/10 min; (2) a density is from 0.940 to 0.960 g/cm | 03-08-2012 |
| 20120000514 | RESIN COMPOSITION FOR SOLAR CELL ENCAPSULANT, SOLAR CELL ENCAPSULANT AND SOLAR CELL MODULE USING THE SAME - A resin composition for a solar cell encapsulant is provided, containing an ethylene•α-olefin copolymer and an organic peroxide or a silane coupling agent or the like, and having superior heat resistance, transparency, flexibility and adhesion property to a glass substrate, as well as good balance between rigidity and cross-linking efficiency, as well as a solar cell encapsulant, and a solar cell module using the same. The resin composition has an ethylene•α-olefin copolymer (A), having the characteristics (a1) to (a4), along with characteristics (a5) or (a6), and an organic peroxide (B) and/or a silane coupling agent (C). | 01-05-2012 |
| 20110257351 | NOVEL TRIARYLPHOSPHINE OR TRIARYLARSINE COMPOUND, ALPHA-OLEFIN POLYMERIZATION CATALYST USING THE COMPOUND, TERNARY COPOLYMER, AND PRODUCTION PROCESS OF ALPHA-OLEFIN -((METH)ACRYLIC ACID)-BASED COPOLYMER - To provide an industrially useful α-olefin.((meth)acrylic acid)-based olefin copolymer having both a high molecular weight and a high comonomer content, a catalyst component capable of realizing a production of two different kinds of α-olefin.((meth)acrylic acid)-based olefin copolymers, and a production process using the catalyst. An α-olefin.((meth)acrylic acid)-based olefin copolymer is produced by using a metal complex complexed with a ligand represented by the following formula (Y is phosphorus or arsenic) for a catalyst composition. | 10-20-2011 |
| 20110213110 | NOVEL METAL COMPLEX AND METHOD FOR PRODUCING ALPHA-OLEFIN POLYMER AND METHOD FOR PRODUCING ALPHA-OLEFIN/(METH)ACRYLATE COPOLYMER USING THE SAME - A novel catalyst component for producing a crystalline α-olefin polymer or α-olefin/(meth)acrylate copolymer having few branches, especially a polymer having a high molecular weight, and a method for producing an α-olefin polymer or an α-olefin/(meth)acrylate copolymer using the catalyst component. | 09-01-2011 |
| 20090082523 | POLYETHYLENE RESIN, PROCESS FOR PRODUCING THE SAME, AND PIPE AND JOINT COMPRISING THE RESIN - The invention relates to a polyethylene resin having excellent slow crack growth property, in particular a resin having excellent durability in a pipe application, which has a specific (a) high-load melt flowrate (HLMFR; HLa), a specific (b) density (Da), and a specific (c) α-olefin content (Ca) and in which (d) a breaking time (T) measured by notched Lander ESCR, the HLa, and the Ca satisfy log T≧−2.9×log HLa+5.1×log Ca+6.8. It further relates to a process for producing the resin and to a pipe and a joint each comprising the resin. | 03-26-2009 |
