Abstract
Mixtures of (A) mixed esters of (a) C.sub.2-10 alkanepolyols, (b) certain dicarboxylic acids, and (c) C.sub.12-30 aliphatic hydrocarbon monocarboxylic acids, said esters having hydroxyl and acid numbers of 0 to 6 and having a molecular weight above 524, and (B) esters of C.sub.32-72 aliphatic monools with C.sub.18-72 aliphatic hydrocarbon monocarboxylic acids (the weight ratio of A to B being between 9:1 and 1:3) are useful as lubricants and detackifiers in thermoplastic molding compositions.
