Method for surface modification of molded article of plastic and method for modifying polymer
An invented method for the surface modification of a molded plastic treats a molded plastic with an oxygen-atom-containing gas such as oxygen, carbon monoxide, a nitrogen oxide, or a sulfur oxide in the presence of N-hydroxyphthalimide or another imide compound represented by the following formula (1): wherein R1 and R2 are each, identical to or different from each other, a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group, a hydroxyl group, an alkoxy group, a carboxyl group, an alkoxycarbonyl group, or an acyl group, or R1 and R2 may be combined to form a double bond or an aromatic or non-aromatic ring; X is an oxygen atom or a hydroxyl group. An invented method for modifying a polymer treats a polymer with an oxygen-atom-containing gas such as oxygen, carbon monoxide, a nitrogen oxide, or a sulfur oxide in the presence of the imide compound represented by the formula (1).
