POLYCARBONATE BLEND COMPOSITIONS CONTAINING RECYCLE FOR IMPROVEMENT IN SURFACE AESTHETICS

摘要

Disclosed herein are compositions and methods for the manufacture of polycarbonate blend compositions containing recycle for improvement in surface aesthetics. The resulting compositions, can be used in the manufacture of articles while still retaining the advantageous physical properties of polycarbonate blend reference compositions that do not contain recycle material. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

主权项

1. A polycarbonate blend composition, comprising:
a. a polycarbonate blend comprising:
i) a first polycarbonate component, wherein the first polycarbonate component comprises a virgin polycarbonate; andii) a second polycarbonate component, wherein the second polycarbonate component comprises a recycled polycarbonate, and wherein the recycled polycarbonate is essentially the same as the virgin polycarbonate prior to recycling; b. an impact modifier blend comprising:
i) a first impact modifier component, wherein the first impact modifier component comprises a virgin impact modifier; andii) a second impact modifier component, wherein the second impact modifier component comprises a recycled impact modifier, and wherein the recycled impact modifier is essentially the same as the virgin impact modifier prior to recycling; wherein a molded part formed from the composition, exhibits less splay than that of a polycarbonate blend reference composition, comprising the same amount of a reference polycarbonate component, consisting essentially of the virgin polycarbonate component in the absence of the recycled polycarbonate, the same amount of a reference impact modifier component, consisting essentially of the virgin impact modifier in the absence of the recycled impact modifier.
