Lubricating and anti-tack compositions useful in the shaping of thermoplastics containing mixed esters and esters of C{HD 32-72 {B monoalcohols with C{HD 18-72 {B monoacids

摘要

Mixtures of (A) mixed esters of (a) C2-10 alkanepolyols, (b) certain dicarboxylic acids, and (c) C12-30 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 C32-72 aliphatic monools with C18-72 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.
