Abstract

PURPOSE: A release agent, excellent in releasability, residual adhesion, solubility in a solvent, etc., which comprises a reaction product from an ethylene/vinyl alcohol copolymer and an alkyloyl chloride.
CONSTITUTION: An ethylene/vinyl alcohol copolymer of the formula [wherein (n+m) is 500W3,000, preferably 800W2,500; n/(n+m) is 0.1W0.9, preferably 0.2W0.6] is dispersed in a dehydrochlorination agent (e.g., pyridine) and the resulting dispersion is reacted, with addition of an alkyloyl chloride (e.g., lauroyl chloride, stearoyl chloride, etc.), at about 80W120°C. After the obtained reaction mixture is cooled to about 50°C, a reaction product separates out with addition of methanol. Purpose product is obtained by the filtering, water washing and drying of the reaction product.
