The present invention relates to compositions containing flame retardant polycarbonate, which are suitable for producing flame-resistant milk-white colored plates. The composition contains polycarbonate, 0.10 to 4.00 weight percent of an acrylate-based scattering additive, 0.50 to 5.00 weight percent of an aromatic-aliphatic polyester, and 0.50 to 8.00 weight percent of a phosphorus-based flame retardant.

Polycarbonate composition having improved flame resistance for extrusion applications

A sheet containing a base layer containing polycarbonate and a flame retardant,  

Polycarbonate plates with improved flame resistance

The present invention relates to a polymer composition containing polycarbonate with a weight-average molecular weight Mw of from 24,000 to 33,000 and 5.0 wt. % to 20.0 wt. % (based on the total amount of the composition) of glass hollow spheres with an alkalinity of less than 1.0 meq/g. The present invention furthermore provides coextruded sheets in which the coextruded layer contains this polymer composition, and shaped articles produced therefrom, in particular containers and pieces of luggage, very particularly suitcases. Sheets which are obtainable with the polymer composition according to the invention have a high mechanical stability, a high scratch resistance, pleasant haptic properties and an excellent homogeneous external visual impression. The present invention furthermore relates to a process for the preparation of these polymer compositions and a process for production of the sheets according to the invention.

Polymer composition having a filler content and coextruded sheet obtainable therefrom

The present invention relates to a method for producing a multi-layer product comprising a) a substrate containing at least one thermoplastic substrate layer and b) at least one protective layer made of a coating composition comprising compounds with at least two functional groups, characterized in that the protective layer(s) are/is applied inline after the production of the substrate containing the substrate layer.

Multi-layer products comprising acrylate containing coatings

The present invention provides a flow-through photobioreactor containing at least one thermoplastic multi-wall sheet having an upper layer and a lower layer having arranged there between at least two sidewalls, at least one inner wall and two or more end caps. Also provided is a process for the production of a biofuel with the inventive photobioreactor. The photobioreactor and process of the present invention have the following advantages: genetically engineered microbes that give higher yields cannot escape into the environment, water in the system does not evaporate, no weeding (presence of unwanted algae), UV light from the sun is filtered out by the reactor walls, temperature control is possible, COfrom power plants, breweries, etc. can be artificially fed to increase yield. The inventive photobioreactor is also less expensive to build than pipe reactors and may have low energy costs to operate, because little or no energy is needed for agitation and pumping in a preferred gravity assisted embodiment.

Photobioreactor for algae growth

A thermoplastic compositions containing polycarbonate and a UV absorbing compound conforming to Formula 1 wherein R denotes a branched or unbranched alkyl group with 4 to 10 carbon atoms is disclosed. The composition is suitable for making molded or extruded articles, including multilayered articles exhibiting improved weatherability.

Compositions containing polycarbonate and novel UV absorbers

A transparent sheet having improved optical properties is disclosed. The sheet that features a deviation angle &#x3b1;(min) according to DIN 52305-A-AS of &#x2266;2.0 and a refracting power D(min) according to DIN 52305-A-AZ of &#x2266;0.05, is prepared by extruding a molding composition comprising linear (co)polycarbonate having weight average molecular weight of 25,000 to 31,000.

Molded polycarbonate articles having improved optical and processing properties

The present invention relates to a single- or multilayer product containing &agr;-olefin-vinyl alcohol copolymers and at least one &agr;-olefin-vinyl acetate copolymer, wherein the amount of vinyl acetate repeat units present in the &agr;-olefin vinyl acetate copolymer is in the range from 35 to 99.99% by weight, and these repeat units have good flexibility which permits processing films or other thin-walled items which are transparent after stretching or thermoforming, and to a process for producing the same, and to their use as packaging films.
