ABSTRACT:
Improved weather resistant products such as building siding, shutters, roof vents and the like, are made by coextruding or laminating a plasticized vinyl chloride capstock with a substrate of rigid vinyl chloride polymers, chlorinated vinyl chloride polymers, or acrylonitrile-butadiene-styrene polymers. The resulting composites are much improved over rigid PVC, chlorinated PVC, or ABS articles alone for retention of appearance and retention of impact on aging.
