Abstract
A polymeric (meth) acrylic composition including polymeric silicone particles and optionally polymeric (meth)acrylic particles. The polymeric silicone particles have a weight average particle diameter between 1 μm and 10 μm and the optional polymeric (meth)acrylic particles have a weight average particle diameter between 20 μm and 100 μm. The polymeric (meth) acrylic composition may be in the form of a masterbatch. A process for making the (meth)acrylic composition including polymeric silicone particles and polymeric (meth)acrylic particles from a polymeric (meth) acrylic masterbatch composition including polymeric silicone particles and optionally polymeric (meth)acrylic particles is provided.
