THERMOPLASTIC COMPOSITION, METHOD OF PRODUCING THE SAME, AND ARTICLES MADE THEREFROM |
摘要 |
A thermoplastic composition comprising the melt blending product of one or more thermoplastic polymers; and from 2 to 20 PHR, of one or more gloss reducing additives wherein each gloss reducing additive comprises a (meth)acrylate copolymer having a glass transition temperature of greater than or equal to 40° C. and 0.001 to 0.04 PHM derived from one or more crosslinking monomers and/or graft-linking agents having two or more ethylenically unsaturated radicals capable of free-radical polymerization, wherein a test specimen produced from the thermoplastic composition has roughness according to DIN 4768 of Ra greater than or equal to 0.6 microns, Rz greater than or equal to 6 microns, Rmax greater than or equal to 7 microns, and a gloss less than 65, 75 degree angle, is provided. Methods for producing the thermoplastic compositions, methods for producing articles from the thermoplastic compositions and such articles are also provided.
