摘要:
The present invention is directed to thermoplastic molding compositions comprising a blend of poly(alkylene terephthalate) and polycarbonate resins characterized in that the weight ratio between said resins is about 1:1 to 4:1 and in that a graft modified polybutadiene rubber is added thereto, said compositions exhibiting an improved level of impact strength.
摘要:
Moulding compositions of polycarbonate, polyalkylene terephthalate and, optionally, polymer having a glass transition temperature below -20.degree. C. may be processed to form particularly low-distortion mouldings when the polycarbonate consists at least partly of o,o,o',o'-tetramethyl-besphenol-polycarbonate.
摘要:
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.

The present invention relates toA. Thermoplastic moulding materials based on polydiorganosiloxane/polycarbonate block copolymers and ABS polymers andB. Thermoplastic moulding compositions based on polysiloxane/polycarbonate block copolymers, elastomeric polymers and, if appropriate, polyalkylene terephthalate.

Processes for the production of polyamides wherein a salt of isophthalic acid and hexamethylene diamine are polycondensed in the presence of formic acid.
摘要:
Polycarbonates are provided based on aromatic bis-hydroxy compounds which contain s-triazine compounds as linking members between 2 mols of the aromatic bis-hydroxy compounds bonded in each case via an oxygen atom thereof, on the one hand, and via carbon atoms of the s-triazine ring, on the other, the s-triazine rings carrying, on at least one further carbon atom, organic radicals with functional groups, these radicals being bonded via oxygen, nitrogen or sulphur. The novel polycarbonates may be used as selective solvents for hydrocarbons mixed with water or for making resins or coatings.

摘要:
The new thermoplastic copolyester carbonates which are based on polybutylene glycols and hexahydrophthalic acid or trimethyladipic acid, as well as admixtures of copolyester carbonates of this type with known polycarbonates are suitable for thermoplastic moulding compositions, particularly where good stability to solvents, such as petrol, is required.
