Abstract: 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.

Abstract: A method for preparing a simultaneous interpenetrating network (SIN) comprising epoxy and vinyl polymers for epoxy thermosets with extended outdoor ultraviolet weatherability produces a durable hybrid network incorporating epoxy resins and vinyl esters. A quantity of epoxy resin is homogenously mixed with the quantity of vinyl ester to form a precured mixture. The precured mixture is cured into an interpenetrating network that is stronger than curing the substances separately. The cured interpenetrating network is a durable coating material that is resistant to damage from environmental exposure, such as ultraviolet light, and resistant to changes in color over time in extended outdoor exposure.
