Meadowfoam monoenoic fatty acid amides as slip and antiblock agents in polyolefin film

摘要

AbstractMixed monounsaturated amides (MMA) of fatty acids from meadowfoam (Limnanthes alba) were effective slip and antiblocking agents for polyethylene films. MMA may compete with extant amides as additives for manufacture of PE films if their selling price is competitive. The MMA (79cis‐5‐eicosenoic acid amides, 17cis‐5‐, andcis‐13‐docosenoic acid amides, and 1cis‐5,cis‐13‐docosadienoic acid amide) required>500 ppm but1000 ppm to give high slip levels within 10 min. Maximum antiblocking effectiveness of MMA, which developed at 1000 ppm, was equivalent to stearamide at 1000 ppm. © 1993 Joh
