Abstract
An additive concentrate composition is composed of a carbonate polymer, a powdered additive such as a pigment, and a mixture of a film-forming adherent such as an esterified polysaccharide and a liquid diluent such as an epoxidized vegetable oil or a bis(phosphorinane), in amounts preferably less than or equal to about 1 percent based on the weight of carbonate polymer and the additive. Alternatively, the epoxidized vegetable oil may optionally be used as a bonding agent. The bonding agents have desirable properties that do not adversely affect the physical properties of the carbonate polymer in end use, and are thermally stable and color-stable.
