摘要

This paper describes acrylic-based resin compositions for use in co-extrusion over various substrates including PVC, ABS and CPVC. These acrylic compositions exhibit significantly improved weathering performance along with excellent impact strength when compared to existing vinyl-based compositions used in applications such as siding, windows and fencing. The acrylic-based compositions require the use of some modifiers to improve impact strength, gloss, flow and other physical properties. A comparison between the modified acrylic-based resin and PVC resin is discussed.
