PURPOSE:To provide the title compsn. having excellent antifungal properties and durability, consisting of a compsn. contg. a vinyl chloride resin and a lactone polymer having side chains or a polycondensate of a hydroxycarboxylic acid. CONSTITUTION:100pts.wt. vinyl chloride resin having an average degree of polymn. of 800-2,000, composed of vinyl chloride (a) and optionally not more than 30wt% comonomer (b) copolymerizable with the component (a) is blended with not less than 25pts.wt., pref. 30-70pts.wt. lactone polymer (c) having side chains (e.g., poly-beta-methyl-delta-valerolactone) or polycondensate (d) having a weight- average MW of not lower than 1,000, obtd. from a hydroxycarboxylic acid (e.g., 3-methyl-5-valeric acid) and optionally not less than 1pt.wt. phosphoric ester (C) (e.g., tricresyl phosphate) and additives (D) such as a plasticizer, a lubricant, a stabilizer, an ultraviolet absorber, a filler, a colorant, etc. |
