Light diffuser composition.

摘要

A light diffuser composition contains a) from 0.1 to 30 weight parts of inorganic particles having an average particle diameter of from 0.1 to 1 micrometer and a refractive index of from 1.9 to 3.2 and b) from 1 to 150 weight parts of polymeric particles having a core/shell morphology with a core of a rubbery vinyl polymer and one or more shells, which particles contain at least 15% of a polymerized alkyl acrylate or alkyl methacrylate, based on the total weight of the particles. The light diffuser composition is useful for preparing a polymer composition which contains a thermoplastic polymer and a) from 0.001 to 0.3% of the inorganic particles a) and b) from 0.01 to 1.5% of the polymeric particles b). Molded articles can be produced from the polymer composition which are particularly useful in lighting applications.
