Abstract:
A method for improving adhesion characteristics of a polymeric material, comprising the steps of:contacting the polymeric material with a composition containing at least one oxidizing agent, said oxidizing agent present in a kinetically degrading state which produces at least one chemical intermediate reactive with the polymeric substrate in a controlled reaction mechanism; andmaintaining contact between the polymeric material and the composition for an interval sufficient to impart functional groups derived from said oxidizing agent into the polymeric material;reacting said oxidizing agent with an activating agent which preferentially reacts with said oxidizing agent to produce said at least one intermediate reactive with the polymeric substrate, said activating agent selected from the group consisting of carboxylic acids, anhydride derivatives of carboxylic acids, acid halide derivatives of carboxylic acids, sulfonic acid derivatives of carboxylic acids, selenic acid derivatives of carboxylic acids, perchloric acid derivatives of carboxylic acid, boric acid derivatives of carboxylic acid, dicarboxylic acid, anhydride derivatives of dicarboxylic acid, acid halide derivatives of dicarboxylic acid, sulfonic acid derivatives of dicarboxylic acids, selenic acid derivatives of dicarboxylic acid, perchloric acid derivatives of dicarboxylic acid, boric acid derivatives of dicarboxylic acid, synthetic equivalents thereof, and mixtures thereof;wherein said reacting step in which said oxidizing agent is reacted with said activating agent occurs in at least one of: an aqueous environment; an anhydrous environment; and a vaporous environment;wherein the reaction between said oxidizing agent and said activating agent occurs at a rate essentially equal to reaction between said polymeric substrate and the reaction intermediate; andwherein said oxidizing agent is a bivalent oxygen compound selected from the group consisting of oxycompounds of chlorine, oxycompounds of bromine, oxycompounds of iodine, oxycompounds of boron, oxycompounds of nitrogen and mixtures thereof.
