ABSTRACT:
Polyester moulding compositions and polyester resins resulting therefrom are rendered fire-protecting by incorporating in the moulding composition a combination of three materials: a source of carbon, such as e.g. pentaerythritol, a source of phosphoric acid, such as e.g. ammonium polyphosphate, and a source of non-inflammable gases such as melamine-formaldehyde, in proportions of 5-20%, 20-40% and 5-20% by weight respectively, calculated on the total weight of this combination plus polyester and monomer.
