The present invention relates to thermoplastic moulding compositions containing polydiorganosiloxane/polycarbonate block copolymers, elastomeric polymers and, if appropriate, polyalkylene terephthalates.

Thermoplastic moulding compositions based on polysiloxane/polycarbonate

Moulding compositions based on polyalkylene terephthalate, polycarbonate, polymer and fluorinated polyolefin have higher Vicat-softening temperature if the polymer and the fluorinated polyolefin are precipitated together from a mixture of the dispersions of both components.

Benzylidenemalonic or vinylogous benzylidenemalonic acid polyesters,

The present invention relates to polycarbonate molding compositions containing additives of alkali or alkaline earth metal salts, tetrahalogenophthalimides and optional glass fibers, characterized in that they contain additive amounts of bromine.

Polycarbonate molding compositions having improved flame retardance

A process for producing an inorganic-organic composition material based on gypsum and polyurethane comprising exposing calcined gypsum or anhydrite to the action of water in the presence of a polyurethane or polyurethane-urea which is dispersible in water and in the presence of up to about 20% by weight (relative to the total mixture) of an alcohol and up to about 20% by weight (relative to the total mixture) of another organic solvent, and allowing the composition to set while permitting any solvents which may be present to evaporate. The calcium sulphate may be on a textile support or the composition may be molded into flexible shaped articles of good mechanical properties.

Compositions which are storage stable at room temperature are made from an organic polyisocyanate, a compound containing at least two isocyanate-reactive groups and a latent catalyst. The latent catalyst is formed from an amine and an alkylating ester of an acid of phosphorus. These compositions react to form isocyanate polyaddition products when exposed to a temperature of 60.degree. C. or higher. These compositions are useful in the production of adhesives, foamed and non-foamed plastics and coatings.

Latent catalysts for the isocyanate polyaddition reaction

Moulding compositions of aromatic polycarbonate, polyalkylene terephthalate and a certain graft copolymer which may be processed into mouldings characterized by high multiaxial impact strength, exhibit an increased Vicat B-temperature if they contain a low amount of an ethylene homo- or copolymer.
