Processes for increasing the chemical resistance of a surface of a formed article are disclosed. The formed article is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a monofunctional benzophenone. The surface of the formed article is then exposed to ultraviolet light to cause crosslinking of the photoactive additive and produce a crosslinked surface. The crosslinking enhances the chemical resistance of the surface. Various means for controlling the depth of the crosslinking are also discussed.

171 Preparation of aromatic polymers US790030 1985-10-22 US4721771A 1988-01-26 Viktors Jansons; Heinrich C. Gors
Aromatic oligomers, in particular arylene ketone and arylene sulfone oligomers, are prepared by reacting an appropriate monomer system in the presence of free Lewis acid and a complex between a Lewis acid, for example, aluminum trichloride, and a Lewis base, for example, N,N-dimethylformamide, and, optionally, a diluent, such as methylene chloride. The process is particularly advantageous for the preparation of substantially or all paralinked arylene ether ketone oligomers as the presence of the Lewis acid/Lewis base complex markedly reduces alkylation and ensures the substantial absence of ortho substitution. The monomer system can be, for example, a self-reacting monomer such as p-phenoxy-benzoyl chloride or a two-monomer system such as 1,4-diphenoxybenzene and terephthaloyl chloride.
