ABSTRACT:
A poly(arylene sulfide) surface is pretreated by contacting this surface with an agent selected from the group consisting of specifically defined halogenated hydrocarbons which are either unsubstituted or substituted with a hydroxy group, organic acids and alkali metal hypohalogenites, with the additional provision that when the poly(arylene) sulfide surface consists of unfilled poly(arylene sulfide), the treating agent is selected from the halogenated hydrocarbons and the organic acids and when the poly(arylene sulfide) surface consists of fiberglass-filled poly(arylene sulfide), this surface is treated with an agent selected from the alkali metal hypohalogenites. The pretreated surface is adhesive-bonded to a solid surface resulting in a bond exhibiting a lap shear strength which is increased as compared to a bond involving the same materials without a pretreatment of the poly(arylene sulfide) surface.
