FATTY ACID BISAMIDE COMPOSITION, AND MOLD RELEASE AGENT, RELEASABLE RESIN COMPOSITION AND MOLDED ITEM EACH OBTAINED USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new mold release agent that exhibits good mold release properties without increasing peeling force with time even when stored in a high-temperature environment. SOLUTION: The fatty acid bisamide composition includes at least one fatty acid bisamide compound represented by general formula [1] below, where the content of the main fatty acid component in the fatty acid bisamide composition is at least 90 area percent and the carbon number of the aliphatic group (R in formula [1]) of the main fatty acid component is at least 19 and at most 23 when the fatty acid bisamide composition is subjected to hydrolysis and the resultant fatty acid component is analyzed by the gas chromatograph/hydrogen flame ionization detection method. R-CONH-(CH2)n-NHCO-R [1] (wherein n is an integer of 1-6; and R is a straight-chain aliphatic group). COPYRIGHT: (C)2009,JPO&INPIT
