摘要
A melt-processable thermoplastic composition is described, which comprises a) 50-99.5 wt. % of a melt-processable thermoplastic polymer and b) 0.5-50 wt. % of a particulate polymer comprising the residues of a monomer mixture comprising 50-100 wt. % of MMA, at least 0-50% of an ethylenically unsaturated comonomer comprising at least one alkyl acrylate or methacrylate and 0-10 wt. % of a copolymerisable cross-linking monomer said particles having a maximum dimension of 5 mm. The compositions have reduced surface gloss and may be useful for forming building components or in any other application in which a low gloss surface is required. A method of making the composition and its uses, for example its use as a capstock material, are also described.
