Patent number: 10550265Abstract: Polycarbonate-containing compositions having desirable properties, such as good resistance to environmental stress cracking, are achieved using a combination of a polycarbonate polymer, a compatibilizing agent and an olefinic elastomer. The polycarbonate-containing composition may include about 40-98 weight percent of one or more carbonates polymers; 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.Type: GrantFiled: August 8, 2018Date of Patent: February 4, 2020Assignee: TRINSEO EUROPE GMBHInventors: Pascal E.
