ABSTRACT:
A process additive for polyolefin films and foams produces products having reduced greasiness and reduced grease-like transfer as compared to glycerol monostearate (GMS). The process additive comprises a fatty acid N-aliphatic alcohol amide of the general formula R--CON(R')R". R is a fatty hydrocarbon radical having from about 8 to 30 carbons. R' typically is hydrogen. R' can also be an alkyl radical of from about 1 to 6 carbons or an alkyl alcohol radical of from about 1 to 6 carbons. R" is an alkyl alcohol fragment of from about 1 to 6 carbons. The alkyl alcohol fragments can be monohydric or polyhydric. Secondary fatty monoalkanolamides in which R' is hydrogen are particularly useful, especially stearamide monoethanolamine (MEA). The benefits of the invention can be achieved and enhanced in some examples by mixing the fatty acid N-aliphatic alcohol amide with an ester of a long chain fatty acid with a polyhydric alcohol, including GMS. Examples of fatty acid N-aliphatic alcohol amides include cocamide MEA, lauramide monoisopropylamine (MIPA), oleamide MIPA, and stearamide 2,3-propanediol.
