Abstract
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.
Claims20
A method of producing a plastic object, the method comprising steps of:
- heating a plastic admixture until the plastic admixture melts, thereby producing a heated admixture, the plastic admixture comprising a plastic and a quaternary phosphonium (QP) salt;
- and
- forming the plastic object from the heated admixture, wherein the plastic object is a heat exchanger.
A method of producing a plastic object, the method comprising steps of:
- heating a plastic admixture until the plastic admixture melts, thereby producing a heated admixture, the plastic admixture comprising a plastic and a phosphonium (QP) quaternary salt;
- and
- forming the plastic object from the heated admixture, wherein the plastic object is a filter media.
A method of producing a plastic object, the method comprising steps of:
- heating a plastic admixture until the plastic admixture melts, thereby producing a heated admixture, the plastic admixture comprising a plastic and a quaternary salt;
- and
- forming the plastic object from the heated admixture, wherein the step of forming of the plastic object from the admixture uses a printer.
A method of producing a plastic object, the method comprising steps of:
- heating a plastic admixture until the plastic admixture melts, thereby producing a heated admixture, the plastic admixture comprising a plastic and a quaternary salt;
- and
- forming the plastic object from the heated admixture, wherein the quaternary salt is selected from a group consisting of a trimethylalkylphosphonium salt, a benzyldimethylalkylphosphonium salt and a benzyltrialkylphosphonium salt.
A method of producing a plastic object, the method comprising sequential steps of:
- heating an organic solvent that comprises a halogen-containing polymer and an aliphatic amino alcohol of general formula HO(CH2)mNH2 where m is an integer from 1-10, thereby producing a first polymer with first hydroxyl groups;
- transforming the first hydroxyl groups to leaving groups;
- adding an amine under conditions that displace the leaving groups and covalently link the amine to the halogen-containing polymer, thereby producing a halogen-containing polymer with quaternary ammonium salts covalently linked thereto;
- heating a plastic admixture until the plastic admixture melts, thereby producing a heated admixture, the plastic admixture comprising the halogen-containing polymer with quaternary ammonium salts covalently linked thereto and a second quaternary salt;
- and
- producing the plastic object from the heated admixture.
