Abstract
The invention relates to compositions and thermoplastic moulding compounds producible therefrom and articles of manufacture in turn based thereupon comprising not only polyethylene terephthalate but also at least one further polyester from the group of the polyalkylene terephthalates or polycycloalkylene terephthalates, also at least one organic phosphinic salt and/or at least one organic diphosphinic salt, melem and melamine polyphosphate.
Claims19
A composition comprising:
- A) at least one polyalkylene terephthalate distinct from polyethylene terephthalate, or polycycloalkylene terephthalate,
- B) polyethylene terephthalate,
- C) at least one organic phosphinic salt of formula (I) and/or at least one organic diphosphinic salt of formula (II) and/or polymers thereof,
- in which
- R1, R2 are identical or different and stand for a linear or branched C1-C6-alkyl and/or for C6-C14-aryl,
- R3 stands for linear or branched C1-C10alkylene, C6-C10arylene or for C1-C6-alkyl-C6-C-10-arylene, or C6-C10-aryl-C1-C6alkylene,
- M is aluminium, zinc or titanium,
- m is an integer of 1 to 4;
- n is an integer of 1 to 3, and
- x is 1 or 2,
- wherein n, x and m in formula (II) may at the same time adopt only integer values such that the diphosphinic salt of formula (II) as a whole is uncharged,
- D) at least one condensed melamine derivative, and
- E) at least one reaction product of a melamine derivative with phosphoric adds or condensed phosphoric adds.
