Abstract: A thermoplastic molding composition comprising polycarbonate resin having improved mold release properties is disclosed the composition contain polycarbonate resin and 0.005 to 5.0% relative to the weight of the composition of at least one hydrocarbon in the form of C15-600-methyl-branched alkane. The hydrocarbon is characterized in that the weight proportion of its branches is 5 to 30 percent relative to the weight of carbons in the alkane chain.

Abstract: The invention relates to a composite sheet which is used to protect displays, especially plasma displays The composite sheet is essentially comprised of three sheets. The inner sheet (1) is made of a thermoplastic synthetic material and the outer sheets (2,3) are made of glass. The individual sheets (1,2,3) are firmly joined to each other by means of a thermoplastic polyurethane film (4). The glass sheet (3) facing the display is provided with electric screening. The inventive sheet, when detached from the display, can be used in a plurality of ways owing to the construction thereof. It is light, shatterproof and offers a wide range of design opportunities.

Abstract: Moldings of mixtures of an aromatic polycarbonate and a thermotropic polymer show a reduced tendency towards delamination when they contain a fluorinated polyolefin and an elastomeric graft polymer.

Abstract: The thermotropic aromatic polyesters according to the invention which contain recurring units corresponding to the following formulae ##STR1## show improved resistance to chemicals, low melting points and, hence, good processibility in addition to the well-known favorable mechanical properties of liquid-crystal materials. The thermotropic aromatic polyesters are used for the production of moldings, filaments, fibers and films.
