Patent number: 7250469Abstract: A fuel tank produced in such a manner that an upper shell and a lower shell melt-molded as two split molded parts from a PPS resin composition are welded to each other at a welding portion. The PPS resin composition contains (a) 60% by weight to 95% by weight of a PPS resin, and (b) 5% by weight to 40% by weight of an olefin resin. The (a) PPS resin contains (a-1) a PPS resin having an MFR of 90 g/10 min to 350 g/10 min and an amount of extracts by chloroform of 2.2% by weight to 4.5% by weight. The (b) olefin resin contains (b-1) a specific olefin copolymer, and (b-2) an ethylene-?-olefin copolymer. The MFR of the PPS resin composition is 15 g/10 min to 50 g/10 min.Type: GrantFiled: April 15, 2004Date of Patent: July 31, 2007Assignees: Toyoda Gosei Co., Ltd., FTS Co., Ltd.Inventors: Daisuke Tsutsumi, Junji Koizumi, Koichiro Hayashi, Joji Kasugai, Masahide Kobayashi

Patent number: 7250470Abstract: A method of nucleating a propylene homo- or copolymer, the method comprising contacting the propylene polymer with a semi-crystalline branched or coupled polymeric nucleating agent under nucleation conditions. In one embodiment, the propylene homopolymer is characterized as having 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In another embodiment, the copolymer is characterized as comprising at least about 60 weight percent (wt %) of units derived from propylene, and as having at least one of the following properties: (i) 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity, (ii) a B-value greater than about 1.4 when the comonomer content, i.e., the units derived from ethylene and/or the unsaturated comonomer(s), of the copolymer is at least about 3 wt %, (iii) a skewness index, Six, greater than about ?1.Type: GrantFiled: February 22, 2006Date of Patent: July 31, 2007Assignee: Dow Global Technologies Inc.Inventors: James C. Stevens, Daniel D. Vanderlende, Patricia Ansems
