包含聚碳酸酯的组成物;POLYCARBONATE CONTAINING COMPOSITIONS

摘要

包含聚碳酸酯的组成物-具有诸如对环境应力裂解之良好耐受性的所欲特性-系使用聚碳酸酯聚合物、相容剂与烯烃系弹性体的组合实现。该包含聚碳酸酯的组成物可包括约40-98重量百分比的一或多个碳酸酯聚合物；约0.1-10重量百分比的一或多个相容剂；与0.1-10重量百分比的一或多个烯烃系弹性体。该包含聚碳酸酯的组成物(譬如聚碳酸酯混掺组成物)较佳具有对中链三酸甘油酯的良好耐化性。该组成物可运用在须耐受医院用清洁流体的构件，例如外壳。举例来说，该组成物可运用在须耐受医院级结核病消毒剂的构件。; about 0.1-10 weight percent of one or more compatibilizing agents; and 0.1-10 weight percent of one or more olefinic elastomers. The polycarbonate-containing compositions (e.g., polycarbonate blend compositions) preferably have good chemical resistance to medium chain triglycerides. The compositions may be employed in components, such as housings, that require resistance to cleaning fluids used in hospitals. For example, the composition may be employed in components that require resistance to hospital grade tuberculosis disinfectants.
