Patent number: 10030135Abstract: Compositions of polymer blends of polyvinylchloride (PVC) or polymethylmethacrylate (PMMA) or polyoxymethylene (POM) and polyhydroxyalkanoate (PHA) are described. In certain embodiments, the PHA is a poly-3-hydroxybutyrate-co-4-hydroxybutyrate copolymer having a weight percent 4-hydroxybutyrate of 30-45%. In other embodiments the PHA is a multiphase P3HB-4HB copolymer blend having one phase fully amorphous. The PHA is mixed with the PVC or PMMA or POM to optimize its optical, thermal and mechanical properties. In certain embodiments, the polymer is branched with optionally additives that improve properties. Methods of making the compositions of the invention are also described. The invention also includes articles, films and laminates comprising the compositions.Type: GrantFiled: October 25, 2016Date of Patent: July 24, 2018Assignee: CJ Cheiljedang CorporationInventors: Roger Weinlein, Yelena Kann

Patent number: 8617344Abstract: The present invention relates to a multistage process for producing hollow plastic articles, encompassing the following steps: a) producing a tubular plastic parison by means of extrusion or coextrusion; b) cutting open the plastic parison to produce two planar-surface parts; c) molding the planar-surface parts in two mold halves to give half shells, where a removable intermediate frame separates the mold halves from one another at least along the peripheral edges, so that the semifinished products/half shells are not in contact with one another; d) opening the mold halves and removing the intermediate frame; e) closing the mold halves, with the result that the half shells come into contact with one another along a peripheral rim; and f) bonding the half shells to give a hollow article.Type: GrantFiled: September 28, 2012Date of Patent: December 31, 2013Assignee: Basell Polyolefine GmbHInventors: Wolfgang Rohde, Jörg Meyer, Rainer Sattel, Jörg Schnorr, Bernhard Springholz, Roger Weinlein, Andreas Wüst

Patent number: 7556489Abstract: The invention relates to a device for partitioning the plastic parisons to give at least one semifinished open-surface product (6), where the device encompasses at least one means of partitioning (3) the plastic parison and one means of drive (2). The means of drive may be composed of one, but preferably of two, driven rolls. It has been found that use of the device of the invention can reduce or prevent the production of creasing and irregularity at the margins, i.e. at the cut edges, of the partitioned parisons, i.e. of the resultant semifinished sheets.Type: GrantFiled: July 9, 2003Date of Patent: July 7, 2009Assignee: Basell Polyolefine GmbHInventors: Wolfgang Rohde, Jörg Meyer, Rainer Sattel, Jörg Schnorr, Bernhard Springholz, Roger Weinlein, Andreas Wüst

Patent number: 5308290Abstract: A belt pulley is described which includes a pulley member and a flanged wheel. The pulley member has a belt-bearing surface and a projection disposed at a position axially adjacent to the belt-bearing surface. The flanged wheel is capable of being assembled separately on the pulley member and includes a spring washer having an inside diameter and an outside diameter. The spring washer is substantially elastically extendable in the area of the inside diameter. The dimensions of the inside diameter are defined such that, upon assembly, the inside diameter elastically extends and touches upon a surface of the projection over at least a portion of the inside diameter such that the flanged wheel is mounted concentrically and non-rotatably in relation to the belt-bearing surface.Type: GrantFiled: March 30, 1993Date of Patent: May 3, 1994Assignee: Firma Carl FreudenbergInventors: Bernhard Gesenhues, Roger Weinlein
