Method for producing a plastic object with embedded quaternary salts
A method for producing customized object is provided. A resin (e.g. plastic or cellulose) is heated and a quaternary salt is added. The resulting admixture is used in forming a material that embodies customized characteristics. In another embodiment, a halogen-containing polymer has a quaternary molecule covalently bonded to it that results in customized properties.
