Abstract: A fabric includes a backing fabric having binding warp yarns, weft yarns, and pile warp yarns interlaced with the weft yarns. In a weft receiving opening, one of the weft yarns is positioned at a back side relative to a weft separating warp yarn extending in the backing fabric in the warp direction and the other weft yarn is positioned at the pile side. A pile warp yarn is interlaced with the weft yarn positioned at the back side relative to the weft separating warp yarn to extend out of the backing fabric between this weft yarn and the other weft yarn. In a transition zone, two transition weft yarns provided immediately adjacent to each other in the warp direction extending through a weft receiving opening are positioned at substantially the same level in a direction that is perpendicular with a plane defined by the warp and weft directions and/or are not separated by a weft separating warp yarn.

Abstract: This invention relates to a mass polymerized rubber-modified monovinylidene aromatic copolymer composition compositions with an improved balance of aesthetic, physical and mechanical properties, in particular, a combination of low gloss and good impact resistance in (co)extruded sheet and thermoformed/vacuum formed articles therefrom. A method for preparing such compositions and articles is disclosed. The improved gloss performance is achieved by maintaining the following relationship between the average rubber particle size (RPS) and the weight average molecular weight (Mw) of the matrix polymer: Mw?155?10?6*RPS6.

Abstract: The present invention is a multistage process for the preparation of a co)polymer composition. Said process comprises the steps of: i) polymerizing in a first stage a reaction mixture comprising one or more monomer with optionally a rubber, a comonomer, a polymerization initiator, a chain transfer agent, a decomposition catalyst and/or a solvent, in the presence of one or more stable free radical precursor which provides a stable free radical during the polymerization process and/or one or more stable free radical such that the polymerization proceeds via a mediated free radical polymerization mechanism until a partial conversion of monomer(s) to (co)polymer is obtained and ii) polymerizing in a second stage the partially converted reaction mixture under reaction conditions that proceed via a free radical polymerization mechanism to obtain a further degree of conversion of monomer(s) to (co)polymer.
