Vinyl chloride polymer/acrylic polymer capstocks

摘要

A composition, particularly suited for forming a surface layer (capstock) with excellent weathering properties of a composite which includes an underlaying layer of PVC or other structural plastic, is comprised of vinyl chloride polymer, an organotin maleate and an acrylic blend of an acylic monomer or copolymer resin and an acrylic weatherable impact modifier.
