PURPOSE: To produce a composition for forming a tube having smooth surface without lowering molding properties of extrusion, by dissolving or swelling an acrylic resin in a plasticizer, blending it with vinyl chloride resin. n CONSTITUTION: An acrylic resin is dissolved or swelled in a plasticizer, and blended with vinyl chloride resin. An acrylic ester (co)polymer, polyacrylic acid methyl ester, etc. shown by the formula CH 2 =CR-COOR 1 (R is H, or lower alkyl; R 1 is 1W18C alkyl) is used as the acrylic resin. ≤100pts.wt. acrylic resin is blended with 100pts.wt. plasticizer and stirred at 20W200°C. n COPYRIGHT: (C)1986,JPO&Japio |
