POLYCARBONATE COMPOSITION COMPRISING TALC

The invention relates to a composition which can be obtained by mixing polycarbonate, non-surface treated talc, and a special anhydride-modified alpha-olefin polymer, wherein the quantities of the talc and the special anhydride-modified alpha-olefin polymer are matched together such that 0.10 to 1.4 wt.% of the anhydride-modified alpha-olefin polymer is used per 10 wt.% of the talc. It could be shown that the decomposition of the polycarbonate can be minimized by means of an in situ surface treatment of the talc with a wax upon mixing with the polycarbonate, and at the same time properties such as the multi-axial impact strength and flowability can be improved. 本发明涉及可通过混合聚碳酸酯、未施胶滑石和特定的酐改性α-烯烃聚合物而得的组合物，其中互相调节滑石和特定的酐改性α-烯烃聚合物的量，以对于每10重量份滑石，使用0.10至1.4重量份的酐改性α-烯烃聚合物。可以表明，通过在与聚碳酸酯混合时才将滑石用蜡原位施胶，可将聚碳酸酯的降解减至最低，并同时可改进如多轴抗冲击性和可流动性之类的性质。
