THE INVENTION
The invention is directed to a thermoplastic molding composition “consisting of” polyalkylene
terephthalate, an oligomeric phosphorous compound having a specific formula alone or in combination
with a second oligomeric phosphorous compound having a different structure than the first phosphorous
compound. The composition additionally consists of a specified amount of magnesium calcium
carbonate hydrate. Other features of the claimed subject matter are set forth the following illustrative
claim.
THE CLAIMS
Claims 14 is illustrative of appellants’ invention and is reproduced below.
14. Thermoplastic moulding compounds consisting of:
A) 30 to 98.9 parts by wt. of polyalkyleneterephthalate:
C) 0 to 30 parts by wt. of a graft polymer;
D) 0.1 to 20 parts by wt. of an oligomeric phophorus compound of the formula (Ia)
