Patent ID: 8609011

Claim:
A process for producing a light scattering complex molding comprising injecting a molding composition into an injection mold to produce the light scattering complex molding, wherein the light scattering complex molding has one or more complex features selected from a varying wall thickness, at least one perforation and at least one non-planar surface, wherein the light scattering complex molding has a varying wall thickness with a minimum to maximum wall thickness ratio of ≧1:4, wherein the molding composition comprises a matrix comprising polymethyl (meth)acrylate and spherical plastic particles embedded therein, wherein the spherical plastic particles have an average particle diameter of 1-24 μm, have a refractive index that differs from the refractive index of the polymethyl(meth)acrylate by 0.01-0.2 and are present in the matrix in an amount of 0.05-30 wt. %, based on the weight of the polymethyl(meth)acrylate, and wherein the spherical plastic particles are spherical silicone particles and are obtained via hydrolysis and polycondensation of (A) an organotrialkoxysilane of formula R 1 Si(OR 2 ) 3 and an organotrialkoxysilane of formula R 1 Si(OR 2 ) 3 or (B) an organotrialkoxysilane of formula R 1 Si(OR 2 ) 3 and a tetraalkoxysilane of formula Si(OR 2 ) 4 , wherein R 1 is an alkyl group or an alkenyl group, and R 2 is an alkyl group.
