PURPOSE: To provide the titled resin compsn. having excellent resistance to weather and impact, moldability, etc., by graft-polymerizing an alkyl methacrylate, etc. onto an acrylic elastomer having a specified composition and blending the resulting polymer with vinyl chloride polymer.
CONSTITUTION: 30W70pts.wt. mixture consisting of 99.9W97wt% C2WC10 alkyl acrylate and 0.1W3wt% crosslinking agent is emulsion-polymerized. 70W30pts.wt. mixture consisting of 99W97wt% alkyl acrylate and 1W3wt% polyfunctional graft-crosslinking agent is polymerized in the presence of the resulting polymer. 25W125pts.wt. monomer mixture contg. alkyl methacrylate as the essential ingredient is graft-polymerized onto 100pts.wt. resulting acrylic elastomer by one- stage or multi-stage polymn. 3W30pts.wt. resulting graft copolymer is blended with 97W70pts.wt.vinyl chloride (co)polymer to obtain the titled resin compsn.
