OXYGEN-CONTAINING PLASMA-POLYMERIZED FILM

摘要

PURPOSE:To obtain the titled polymerized film effective in improving the surface properties of a molded article, by carrying out a low-temperature treatment of an article in a gas containing a specific compound and an alkylene oxide having a specific total carbon number in the molecule. CONSTITUTION:The objective polymerized film can be produced by the low- temperature plasma treatment in a gas containing an alkylene oxide having a total carbon number of 2-5 and/or a compount of formula (R1-R3 are H or 1-5C alkyl; at least one of R1-R3 is alkyl; n is 1-3) (e.g. ethylene glycol monomethyl ether) or formula C3H5(OR4)3 (R4 is H or 1-5C alkyl). USE:Suitable as a gas-separation membrane, etc.
