摘要:
The present invention relates to new flameproofing agent combinations of bisphthalimides and tetrafluoroethylene polymers and their use for providing thermoplastic moulding compositions of halogenated polycarbonates and ABS polymers with a flame-repellent finish.
摘要:
The present invention relates to thermoplastic moulding compositions which are provided with a flame-repellent finish by adding phosph(on)ate esters, tetrafluoroethylene polymers and, if appropriate, halogen compounds.
摘要:
The invention relates to polycarbonate molding compounds consisting of halogen-free polycarbonates, graft polymers, phosphorus compounds, tetrafluoroethylene polymers and, optionally, copolymers and/or, optionally, other additives known per se and a process for their production.
摘要:
The present invention relates to the use of a copolymer with an Mw of 2.times.10.sup.6 to 1.times.10.sup.7 in amounts of 0.5 to 5 parts by weight for improving the heat distortion point of thermoplastic mixtures containing polycarbonates, graft polymers and copolymers, and the thermoplastic mixtures correspondingly rendered dimensionally stable under the influence of heat.
摘要:
The invention relates to thermoplastic polycarbonate molding compositions containing polycarbonates, special siloxane-containing graft polymers and, optionally, lower thermoplasts and/or standard additives and to a process for the production of the polycarbonate molding compositions.
摘要:
The present invention relates to thermoplastic moulding compositions containing thermoplastic polycarbonates, graft polymers, rubber-free copolymers and, if appropriate, copolymeric rubbers, and also, if appropriate, conventional additives, which are characterized in that the rubber-free copolymers contain internal epoxide compounds.
摘要:
Particularly high-grade blends of thermoplastic polycarbonates, graft copolymers and, optionally, further thermoplastic resins, useful as moulding materials with good low-temperature impact strength and resistance to ageing and light, which yield mouldings with superior surfaces, are obtained from graft bases which are silicone rubbers containing sulphur in addition to groups containing carbon double bonds.
摘要:
The present invention relates to thermoplastic moulding compounds based on thermoplastic polycarbonates, graft polymers and optionally thermoplastic copolymers, characterized in that the graft polymers contain at least one primary or secondary aliphatic acrylic acid ester or tert.-butyl acrylate or tert.-butyl methylacrylate incorporated by polymerization. The invention also relates to a process for the preparation of these thermoplastic moulding compounds.

The present invention relates to thermoplastic moulding compositions containing thermoplastic polycarbonates, graft polymers, rubber-free copolymers and, if appropriate, copolymeric rubbers, and also, if appropriate, conventional additives, which are characterized in that the rubber-free copolymers contain internal epoxide compounds.
摘要:
The present invention relates to thermoplastic moulding compositions consisting of polycarbonates, graft polymers and copolymers, which are characterized in that they contain special graft polymers and/or special copolymers, with the result that these moulding compositions possess a very homogeneous rubber distribution and furthermore possess very good toughness and heat stability and substantially improved heat distortion resistance.
