Abstract
PURPOSE: To provide polyvinyl chloride with improved impact resistance and reduced amounts of inorg. filler added by blending fine calcium carbonate and silicon acid hydrate with polyvinyl chloride.
CONSTITUTION: 5W24pts. of fine calcium carbonate and 0.1W5pts. of silicon acid hydrate with specific surface area of 120W220m2/g, pref. 130W180m2/g, are blended with 100pts. of polyvinyl chloride. As calcium carbonate to be applied, fine calcium carbonate subjected to activating treatment by aliphatic acid such as stearic acid, palmitic acid or the like is pref. used. If the specific surface area of silicic acid hydrate is lower than the above-described lower limit, impact resistsnce is not sufficiently improved and, if higher than the upper limit impact resistance is not sufficiently improved as well.
