  • Method of loading nicotine into porous polymeric items
    Patent number: 4736755
    Abstract: A method of loading nicotine into porous polymeric items consisting essentially of a polyolefin. The method comprises contacting the items with nicotine or nicotine dissolved in a carrier. The polyolefin item, preferably polyethylene or polypropylene, may be loaded with nicotine by several variations on the basic method. The items may be emplaced in a vessel with nicotine and the vessel then closed for a period of time prior to removal of said items.A preferred method of producing porous polyethylene items loaded with nicotine comprises first emplacing porous polyethylene items in a vessel. A solution comprising between about 1% nicotine and about 10% nicotine and a solvent for nicotine demonstrating an adherence for polyethylene surfaces is prepared. A quantity of this solution sufficient to contact at least a majority of the polyethylene items is added to the vessel.
