An extruded polymeric article having a frosted and textured surface appearance comprised of a polymeric matrix and polymeric particles, wherein said polymeric particles are substantially spherical, highly crosslinked, have a mean particle size of between 15 and 70 micrometers, and have a particle size distribution between 10-110 micrometers, wherein the article has a Haze number as determined by ASTM D1003 of at least 90% and a minimum surface roughness of 0.5 micrometers to 30 micrometers as measured using ASME methods B461.1, B461.2 and Y14.36, and wherein said polymeric matrix and polymer particles have a mismatch of refractive indices in which the difference in refractive index between the polymeric matrix and polymer particles is greater than 0.015.
A resin comprised of a polymeric matrix and polymeric particles wherein said polymeric particles are substantially spherical, highly crosslinked, have a mean particle size of between 15 and 70 micrometers and have a particle size distribution between 10-110 micrometers, wherein a 0.125 inch thick sheet extruded from said resin has a Haze number as determined by ASTM D1003 of at least 90% and a minimum surface roughness of 0.5 micrometers to 30 micrometers as measured using ASME methods B461.1, B461.2 and Y14.36, and wherein said polymeric matrix and polymer particles have a mismatch of refractive indices in which the difference in refractive index between the polymeric matrix and polymer particles is greater than 0.02.
