ABSTRACT:
The invention relates to polymer mixtures which comprise a polyester, glass fibres, a brominated polystyrene and talcum. By using milled glass fibres a polymer mixture is obtained having a high tracking index, good flame-retarding properties and a great rigidity. The invention also relates to articles formed from such polymer mixtures and to a method of preparing the polymer mixtures according to the invention.
