Disclosed herein are compositions including a thermoformable sheet having three of more layers. Two layers include one or more monovinylidene aromatic monomer containing polymers which are impact modified by a rubber, one or more monovinylidene aromatic monomer and unsaturated nitrile containing copolymers, or a blend of one or more monovinylidene aromatic monomer containing polymers and a polyolefin, which exhibit resistance to environmental stress cracking. At least one of the two layers is an outer layer. An inner layer includes post-consumer recycled monovinylidene aromatic monomer containing polymers which are impact modified by a rubber, post-industrial recycled monovinylidene aromatic monomer containing polymers which are impact modified by a rubber. Optionally, the composition may include virgin monovinylidene aromatic monomer containing polymers which are impact modified by a rubber. Optionally, the composition may include an outer layer which is a gloss layer.

A composition includes one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds containing nucleophilic groups, and the copolymer has on average about 0.01 to about 15.0 percent by weight of nucleophilic groups pendant from the copolymer. The copolymer is chain extended and/or branched by one or more copolymers of one or more vinylidene aromatic monomers and one or more unsaturated compounds having electrophilic groups, or a portion of the chains of the copolymer of one or more vinylidene aromatic monomers and one or more nucleophilic groups are crosslinked with other chains of the copolymer of one or more vinylidene aromatic monomers and one or more nucleophilic groups by ionic bonding of anions formed from the pendant nucleophilic groups with a metal cation having a valence of 2 or greater or complexation between pendant acid groups and metal oxides.

A polycarbonate article is described that is formed from a thermoplastic composition comprised of a polycarbonate or polycarbonate copolymer; and at least 1% by weight of a polysilsesquioxane (PSQ) solid particles that have a decomposition temperature of at least 350&#xb0; C. and an acicular filler, which desirably has an aspect ratio of 2 to 50. The PSQ particles are desirably spherical. The article is formed by heating the composition and shaping the heated composition, wherein the article and the filler and PSQ particles are dispersed therein, wherein the PSQ particles desirably maintain their spherical morphology.

Matte polycarbonate compositions, articles and method to make them

A composition comprising one or more polymers consisting of polycarbonate or a copolymer of greater than 50 mole percent of polycarbonate units and less than 50 mole percent of monomer units which copolymerize with polycarbonate units; 5 to 20 percent by weight of one or more minerals containing high aspect ratio CaSiO, optionally a buffering agent for basic materials and optionally one or more antioxidants useful with polycarbonate containing compositions. Also disclosed are sheets containing one or more layers of this composition. The sheets exhibit matte surface appearance and are easily recyclable.

High impact polystyrenes and related monovinyl aromatic polymers generally have either a high modulus or good resistance to environmental stress cracking. The present invention is directed at polymeric materials having both a high modulus and good resistance to environmental stress cracking thus enabling the down gauging of parts, and or the use of the materials in new applications. The invention is predicated on the use of one or more, or even all of the following features: a high molecular weight matrix polymer, reduced concentration of elastomeric polymer, or methods that result in large rubber particle size.

A floor mat includes a plurality of projections integrally formed and extending from a lower surface. At least some of the projections have a straight axis and a cross section perpendicular to the straight axis that decreases from the base to the tip of the projection. The at least some projections have a height measured along the axis and a width corresponding to its largest dimension measured parallel to a plane of the lower surface such that the ratio of the width to the height of the projection is greater than 1.
