PROCESSES FOR ENHANCING FLAME RETARDANCE AND CHEMICAL RESISTANCE OF POLYMERS
摘要
Processes for increasing the chemical resistance of a surface of a formed product are disclosed. The formed product is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a dihydroxybenzophenone. The surface of the formed product 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.
