Abstract: The present invention relates to 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 having a surface modified with an organic modifier of formula (I), an organic modifier of formula (I) being the only organic modifier used to modify a surface of the solid particulate material, 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, (I) where R is selected from a quaternary ammonium cation, a quaternary phosphonium cation, and imidazolium cation and a pyridinium cation; x is an integer ranging from 1-5; Ry is selected from OH, C(O)OH, NH2, SH and CH3; and Z is a counter anion.
