POLYMER ALLOY COMPOUND SUITED FOR INJECTION MOLDING

摘要

A polymer alloy composition suitable for injection molding comprising about 2 to 18% methylmethacrylate, 70 to 80% styrene, and 10 to 22% butadiene by weight of the total composition which is particularly suitable for molding toothbrush handles and methods of preparing toothbrush handles comprising blending the polymer components above the melting point of the polymer mix, introducing the molten polymer alloy into an injection mold designed to produce a toothbrush handle, and cooling the injection mold to form a toothbrush handle.
