<p>A thermoplastic molding composition which features improved dimensional stability and low gloss is disclosed. The composition which contains (A) a first grafted rubber having a weight average particle size of 0.05 to 0.30 microns, (B) a second grafted rubber having a weight average particle size of 0.31 to 1.00 microns, (C) vinyl chloride (co) polymer, and, optionally, (D) styrene copolymer, is especially suitable for extruding profiles. In a preferrred embodiment, at least one of the grafted rubbers is characterized in that its substrate features a core-shell structure, wherein the core contain at least one crosslinked vinylaromatic polymer, and the shell is elastomeric.</p> |
