Beschreibung
Zusammenfassung:	Vinyl copolymer compositions, especially ASA compositions, exhibit improved weatherability and color retention performance when processed according to the invention. Disclosed herein is a method of improving the weatherability and color retention performance of vinyl copolymer compositions and exterior siding incorporating such vinyl copolymer compositions. More specifically, a method is disclosed comprising improving the weatherability and color retention of vinyl copolymer compositions, especially ASA compositions, which is advantageous with respect to cost and ease of manufacturing. Composite articles are also disclosed incorporating the foregoing improved vinyl copolymer compositions as an exterior layer.
