Production of agricultural film excellent in antifogging and anticlouding property

Abstract

Abstract PURPOSE: To produce an agricultural film which can prevent fogging in an agricultural house and has an excellent anticlouding property for a long time, by adding a specified fluorine compound and a sorbitan fatty acid ester each in a specified amount to a vinyl chloride resin. CONSTITUTION: The title film is produced by adding a fluorine compound (A) of formula I (wherein R f is a 6W10C perfluoroalkyl, and n is 5W30), a compound of formula II, a sorbitan fatty acid ester (B) [e.g., sorbitan palmitic acid (1.2mol.) ester] at a weight ratio of A to B of 50:50W10:90. By using this agricultural film, it is possible to perfectly prevent fogging encountered in an agricultural house from late autumn to winter, and this film can exhibit an excellent anticlouding property for a long time.
