Abstract
A thermoplastic additive composition comprises an acetal compound and at least one co-additive. The acetal compound can be the product of the reaction between an alditol or a C1-substituted alditol and a benzaldehyde. The co-additive can be a fatty acid amide compound, a fatty acid ester compound, and/or a fluoropolymer. A thermoplastic composition comprises a thermoplastic (e.g., one or more polyolefins) and an additive composition as described above.
Claims11
A thermoplastic additive composition comprising:
- (a) an acetal compound conforming to the structure of Formula (II)
- wherein n is 0, 1, or 2;
- R1 is selected from the group consisting of alkyl groups, alkenyl groups, alkoxy groups, and alkyl halide groups;
- and R2, R3, R4, R5, R6, R7, R8, R9, R10, and R11 are each independently selected from the group consisting of hydrogen, alkyl groups, alkenyl groups, alkoxy groups, carboxyl groups, halogens, and phenyl groups;
- and
- (b) a fatty acid ester compound, wherein the fatty acid ester compound is the product of the reaction between a C10-C22 fatty acid and a compound selected from the group consisting of glycerol and diglycerol and the fatty acid ester compound comprises about 80 wt. % or more monoester, based on the total weight of the fatty acid ester compound present in the additive composition,
- wherein the acetal compound comprises about 60 to about 90 wt. % of the additive composition and the fatty acid ester compound comprises about 10 to about 40 wt. % of the additivie composition, based on the total weight of the acetal compound and fatty acid ester compound present in the additive composition.
