Disclosed is a polymeric article having a frosted and/or surface textured finish made from a polymeric resin comprised of a polymeric matrix and polymeric particles which 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.

Process for preparing beads based on acrylic polymers which comprises the preparation of microbeads from 10 to 40 micron by means of a polymerization process in suspension of acrylic monomers in the presence of at least a crosslinking monomer at least bifunctional, characterized in that a second polymerization of the acrylic monomers is carried out in absence of crosslinking monomers and using as suspending phase a fraction of the suspension obtained in the preceding polymerization containing a crosslinking agent, said fraction containing an amount of microbeads comprised between 3 and 40% by weight with respect to the final polymer obtained in the second polymerization.
