Beschreibung
Zusammenfassung:	A thermoplastic composition includes: a thermoplastic polymer including from about 30 wt% to about 90 wt% poly(methyl methacrylate) (PMMA) and from about 5 wt% to about 70 wt% of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 20 wt% to about 60 wt%; and a plurality of photoluminescent materials. A method of forming a thermoplastic composition includes: (a) forming a poly(carbonate-siloxane) copolymer by forming siloxane-chloroformate prior to copolymerizing the poly(carbonate-siloxane) copolymer, wherein the poly(carbonate-siloxane) copolymer has a siloxane content of from about 20 wt% to about 60 wt%; (b) combining from about 5 wt% to about 70 wt% of the poly(carbonate-siloxane) copolymer with from about 30 wt% to about 90 wt% poly(methyl methacrylate) (PMMA) to form a polymer composition; and (c) combining a plurality of photoluminescent materials with the polymer composition to form the thermoplastic composition.
