ABSTRACT:
The present invention provides a process for generating a reagent of sulfur trioxide in a carrier. A source of sulfur trioxide, a carrier, and oleum are introduced into a reagent generator. The sulfur trioxide, carrier, and oleum are then contacted to provide a reagent of sulfur trioxide in the carrier. Separate oleum and sulfur trioxide in carrier phases are formed, and oleum is removed from the reagent generator. The sulfur trioxide in carrier reagent is then ready to be used, preferably in a process to treat the surfaces of polymeric resin material such as medical devices fabricated from a variety of polymeric resins. The carrier may be either a liquid halocarbon solution or an inert gas.
