Claims
- 1. Thermoplastic moulding compounds consisting essentially of
- A. from 50 to 90 parts by weight of a fully aromatic polyester carbonate,
- B. from 10 to 50 parts by weight of one or more thermoplastic polyalkylene terephthalates and
- C. from 3 to 40 parts by weight of a graft polymer consisting of
- C.1 from 5 to 90 parts by weight of a mixture of
- C.1.1 from 20 to 99 parts by weight of methyl methacrylate and
- C.1.2 from 1 to 40 parts by weight of the acrylic acid ester of a primary or secondary monohydric aliphatic C.sub.2 -C.sub.10 alcohol in which the sum of the parts by weight of C.1.1 and C.1.2 amount to 100 parts by weight, on
- C.2 from 10 to 95 parts by weight of a cross-linked diene rubber having an average particle diameter of d.sub.50 of from 0.05 to 1 .mu.m and a gel content of more than 50% by weight, based on the weight of C.2,
- in which the sum of the parts by weight of A, B and C is 100 parts by weight.
- 2. Process for the preparation of the moulding compounds according to claim 1, characterized in that components A, B and C and optionally stabilizers, pigments, mould release agents, flame retardants or antistatic agents or mixtures thereof are mixed together in known manner and melt compounded or melt extruded at elevated temperatures in conventional apparatus.
- 3. Moulding compounds according to claim 1, characterised in that the graft polymer C is prepared from 10 to 70 parts by weight of graft monomer C.1 and 30 to 90 parts by weight of the diene rubber C.2.
- 4. Moulding compounds according to claim 1 characterised in that component C.1 consists of 50 to 97 parts by weight of C.1.1 and 1 to 20 parts by weight of C.1.2.
- 5. Moulding compounds according to claim 1, characterised in that particle diameters of the diene rubbers C.2 are from 0.05 to 0.8 .mu.m.
- 6. Moulding compounds according to claim 1, characterised in that the gel content of the diene rubber C.2 is more than 70% by weight, based on C.2.
- 7. Moulding compounds according to claim 1, characterised in that, in addition, they contain at least one additive selected from stabilizers, pigments, mould release agents, flame retardants and antistatic agents.
