Abstract: A thermoplastic composition includes: a transparent thermoplastic resin; from about 0.1 wt % to about 2 wt % of a mold release agent including pentaerythritol tetrastearate (PETS); and from 0.01 wt % to about 5 wt % of a stabilizer component. The PETS is derived from an aliphatic carboxylic acid having less than 50 wt % content of C18 or longer alkane chains. The thermoplastic composition has improved transparency properties as compared to comparative compositions including PETS derived from an animal source.

Abstract: Thermoplastic compositions include: (a) from about 5 wt% to about 95 wt% of at least one recycled polycarbonate comprising a post-consumer recycled (PCR) polycarbonate; and (b) from about 0.01 wt% to about 2 wt% of an acid component. The post-consumer recycled (PCR) polycarbonate comprises at least 10 mol% —OH endgroup content. In certain aspects the acid component 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.
