Abstract
A method for manufacturing vinyl chloride-butyl acrylate graft copolymers for processing by injection molding is provided wherein vinyl chloride is grafted onto crosslinked polybutyl acrylate in the presence of chain regulators. The graft copolymers exhibit excellent flow characteristics as a melt and provide molded parts with good surface quality and excellent mechanical properties.
