Claim Text:
1. A thermoplastic composition comprising: (A) from 55 to 95 percent by weight of a thermoplastic matrix comprising one or more thermoplastic polymers; and (B) from 5 to 45 percent by weight of a dispersed phase which comprises a crosslinked (meth)acrylate copolymer, wherein the (meth)acrylate copolymer comprises at least 95 percent by weight derived from methyl methacrylate units and from greater than zero to less than 0.5 percent by weight derived from ethylene glycol dimethacrylate (EGDA) and from 0.1 to 1 percent by weight of butyl mercapto propionate (BMP) as a chain-transfer agent; wherein the difference in refractive index between components (A) and (B) is greater than 0.08 and wherein the thermoplastic composition has a Flop Index value in the range of from 4 to 10.
