Description
技术领域
本发明涉及聚碳酸酯模塑组合物,其包含铝化合物,具有改进的机械性能和改进的抗静电作用。
背景技术
热塑性模塑组合物,特别是包含一种或多种烯键式不饱和单体的均-和/或共聚合物、聚碳酸酯和聚酯的那些,可以从许多出版物中已知。对于ABS聚合物的使用更是如此。下列文献仅仅是以举例的形式列出以供参考:DE-A 19616、WO 97/40092、EP-A-728811、EP-A-315868(=US-A-4937285)、EP-A-0174493(US-P 4983658)、US-P 5030675、JA 59202240、EP-A-0363608(=US-P 5204394)、EP-A 076 7204、EP-A0611798、WO 96/27600和EP-A 0754。
在该现有技术中描述的热塑性模塑组合物仍然在机械性能方面需要改进。当将这些模塑组合物用于与安全有关的组件例如用于机车工业时更是如此,这些领域对断裂伸长、ESC性能、缺口冲击强度、热变形温度和可加工性具有很高的要求。
此外,已知的模塑组合物的抗静电作用也仍然需要改进。
发明内容
令人惊奇的是,现已发现,如果向聚碳酸酯模塑组合物中加入铝化合物,则聚碳酸酯模塑组合物就具有抗静电作用和改进的机械性能。
因此,本发明提供了热塑性模塑组合物,其中含有热塑性聚碳酸酯和就每100重量份聚碳酸酯而言0.01-30、优选0.01-20、特别优选0.01-10重量份的铝化合物,该铝化合物的平均粒径为1nm-20μm,优选1nm-10μm,特别优选5-500nm和尤其优选5-200nm。

C.0.5-60、优选1-40、特别优选2-30重量份的包含至少两种选自下列的单体的接枝共聚物:单一或多不饱和烯烃例如乙烯、丙烯、氯丁二烯、丁二烯和异戊二烯、醋酸乙烯酯、苯乙烯、α-甲基苯乙烯、环被取代的苯乙烯、乙烯基氰化物例如丙烯腈和甲基丙烯腈、马来酸酐和N-被取代的马来酰亚胺,
D.0.01-30、优选0.01-20、特别优选0.01-10重量份的铝化合物,该铝化合物的平均粒径为1nm-20μm、优选1nm-10μm、特别优选5-500nm和尤其优选5-200nm。
