Production of scratch-resistant polycarbonate moulded parts

Polyisoolefins are obtained using the process according to the invention by polymerising isoolefins, optionally with conjugated or unconjugated dienes and/or cationically polymerisable, mono- or polyunsaturated compounds at temperatures of -100.degree. C. to +100.degree. C. and pressures of 0.1 to 100 bar in solution, in suspension or in the gas phase in the presence of initiator systems consisting of certain hydrocarbons and open-chain and/or cyclic aluminoxane compounds.

Process for the production of polyisoolefins

A thermoplastic molding composition containing an aromatic polycarbonate and a particular siloxane compound is disclosed. The composition which is based on a polycarbonate resin having bifunctional structural units corresponding to formula (Ia) ##STR1## wherein R.sup.1 and R.sup.2 denote, independently of one another, hydrogen, halogen, C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.6 -cycloalkyl, C.sub.6 -C.sub.10 -aryl, or C.sub.7 -C.sub.12 -aralkyl,

Stabilization of polycarbonates having high heat distortion temperatures

The invention relates to mixtures of special polyesters and/or special polyester carbonates with amorphous thermoplastics and/or with partly crystalline thermoplastics and/or with rubbers and/or with graft polymers useful for molding articles.

Thermoplastic blends containing polyesters and polyester carbonates

The invention relates to readily processible polyamide molding compounds which have very good mechanical and electrical properties as well as high surface quality and are based on polyamide, magnesium hydroxide and polyhydroxy compounds of the Novolak type.

Highly flame-retardant polyamide moulding compounds

The present invention relates to a process for producing polymer blends from polycarbonate and mass-polymerized ABS by the condensation of oligocarbonate in the presence of mass-polymerized ABS.

The present invention relates to easily processable polyamide moulding materials with very good mechanical and electrical properties based on calcium magnesium carbonate hydrate as the flame-retardant additive.

Difficultly flammable polyamide moulding materials

A process for the production of polycarbonates by melt transesterification is disclosed. Accordingly, polycarbonate waste is dissolved in monophenols and at an elevated temperature and in the presence of a catalyst degraded to yield oligocarbonates, diaryl carbonates and diphenols. Following the optional separation of fillers and other additives there is produced by partial recondensation and the distillation of monophenol a higher viscosity oligocarbonate having a OH and aryl carbonate terminal groups and a weight average molecular weight of 8000 to 18000, the oligocarbonate thus produced is then polycondensed to form a polycarbonate resin.

Process for the production of thermoplastic polycarbonates

A two step solvent-free process for the preparation of polycarbonates having a low degree of branching is disclosed. Accordingly, the process comprise
