Abstract
There is provided by the present invention aromatic polyester-siloxane block copolymers which can be made by effecting the condensation between tetramethyldisiloxane bisbenzoic acid or acid chloride with a dihydric phenol such as bisphenol A or in combination with a mixture of such tetramethyldisiloxane bisbenzoic acid and aromatic acids, such as terephthalic acid or isophthalic acid. The aromatic polyester-siloxane block copolymers can be used as molding compounds, extruded films, in making composite matrix materials and as flame retardants for aromatic polycarbonates.
