Claim:
1. A polymer composition having improved scratch resistance properties, the composition comprising (i) one or more polymers with a glass transition temperature (Tg) of at least 25° C., and (ii) solid particulate material comprising a surface modified with an organic modifier of formula (I), wherein the organic modifier of formula (I) is the only organic modifier used to modify a surface of the solid particulate material, and wherein the solid particulate material is distributed at least throughout a surface layer of the one or more polymers, and wherein the improved scratch resistance is relative to that of the one or more polymers absent the distributed particulate material, where R is selected from a quaternary ammonium cation, a quaternary phosphonium cation, an imidazolium cation and a pyridinium cation; x is an integer ranging from 1-5; R
