ANTISTATIC PLASTICIZER AND CHLORINE-CONTAINING RESIN COMPOSITION USING THE SAME

PROBLEM TO BE SOLVED: To obtain a plasticizer which improves compatibility with chlorine- containing resins and antistatic properties by adding one or more compounds selected from alkali metal salts and alkaline earth metal salts to a dibasic acid diester. SOLUTION: An antistatic plasticizer is obtained by adding 0.05-10 pts.wt. of one or more compounds comprising a cation part of an alkali metal or alkaline earth metal such as Na and Ca and an anion part such as Cl and CO3 to 100 pts.wt. of a compound of the formula. 100 pts.wt. of a chlorine-containing compound such as polyvinyl chloride and chlorinated polyethylene is blended with 0.1-100 pts.wt. of the compound of the formula, alkali metal salts and the like to obtain a composition. The compound of the formula is obtained by reacting a dibasic acid such as adipic acid and phthalic acid and an alcohol such as 2-(2-butoxyethoxy)ethanol and 2-butoxyethanol. In the formula, X is a 2-8C alkylene, a dibasic acid residue or the like; R1 and R2 are each a 1-9C alkyl; A is a 2-4C alkylene; and n is 1-7.
