  • Light diffusing polymer composition, method of producing the same, and articles made therefrom
    Patent number: 9029476
    Abstract: A composition comprising: a blended product of: a matrix polymer; and from 0.05 to 2.5 wt % diffuser polymeric particles, wherein the diffuser polymeric particles are characterized by an average diameter from 2.0 to 8 micrometers, a particle size distribution such that at least 90 wt % of the polymer particles fall within ±30% of the volume average particle size, a refractive index, RI, from 1.50 to 1.55; a crosslinking level great than 4%; and wherein the diffuser polymeric particles are produced using at least one alkyl(meth)acrylate monomer copolymerized with from 5 wt % to 25 wt % crosslinking monomer selected from the group consisting of aliphatic crosslinking monomers, aromatic crosslinking monomers, and combinations thereof, and optionally, one or more comonomers selected from the group consisting of aryl(meth)acrylate monomers and monovinyl arenes is provided.
