摘要:
The invention relates to flame-resistant poly-carbonate/ABS molding compounds which are considerably improved in their mechanical properties and thermal stability by an addition of polyalkylene terephthalate and an oligomeric phosphate.
摘要:
The invention relates to flameproofed polycarbonate/ABS blends which are resistant to stress cracking, wherein the polycarbonates are wholly or partly modified by halobutyl rubber blocks.
摘要:
The invention relates to mixtures of polycarbonate, phenolically hydroxyfunctional branched dimeric fatty acid polyesters and optionally graft polymer, which are distinguished by a good low-temperature strength and stress cracking resistance and good mould release properties.

Thermoplastic molding compounds containingA. 10 to 99 parts by weight polycarbonate or polyester carbonateB. 0 to 90 parts by weight of a rubber-free resin compatible or partly compatible with component A.,C. 0 to 90 parts by weight of a rubber-modified resin compatible or partly compatible with component A.,D. 0.5 to 10 parts by weight, based on 100 parts by weight of A+B+C, of a rubber component having a glass transition temperature below 0.degree. C. which is incompatible with component A,characterized in that component D is used in the form of a powder mixture D* produced froma. 1 to 50 parts by weight of an ungrafted particulate rubber component having a glass transition temperature below 0.degree. C. and an average particle diameter d.sub.50 of 0.05 to 5 .mu.m in latex form andb. 50 to 99 parts by weight of component B, component C or a mixture of components B and C in latex form,the components mentioned under a. and b. initially being mixed with one another as latices and then being worked up together to form a powder mixture D*.
