Particulate polymer composition, a method of making particulate polymer compositions, and light-scattering thermoplastic polymer compositions containing the particulate polymers

摘要

A particulate polymer composition comprising core/shell polymer particles in a size range between 2 and 15 micrometers, and having a core with a refractive index close to, but not identical with, that of a matrix polymer and an outer shell compatible with the matrix polymer, imparts light-diffusing properties to the matrix polymer without degrading its physical properties.
