Abstract

Thermoplastic compositions include: (a) from about 5 wt% to about 95 wt% of at least one recycled polycarbonate; and (b) from about 0.01 wt% to about 2 wt% of an acid quencher. The at least one recycled polycarbonate may include in some aspects a post-consumer recycled (PCR) polycarbonate. In certain aspects the acid quencher includes mono zinc phosphate (MZP), a liquid solution comprising phosphorous acid, or a combination thereof. The compositions have improved hydro-aging properties as compared to conventional compositions that include recycled polycarbonate.
