The present invention relates to thermoplastic moulding compositions containing (A) 20 to 80 parts by weight of a polydiorganosiloxane/polycarbonate block copolymer, (B) 70 to 5 parts by weight of a graft polymer in particle form and (C) 5 to 60 parts by weight of a rubber-free, thermoplastic vinyl polymer, the total of parts by weight of components (A)+(B)+(C) being in each case 100 parts by weight, and, if appropriate, other known additives.
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.
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:
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.
