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.
Claims21
A method of producing a polymeric 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 hydroxyl groups;
- transforming the 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.
A plastic composition comprising a halogen-containing plastic covalently bound to a sidechain, wherein the sidechain has a structure of:
- wherein m is an integer from 1-10, and R, R′ and R″ are independently selected alkyl, alkenyl or alkynyl groups, provided R has at least ten carbons but twenty-two or fewer carbons and R′ and R″ both have at least one carbon but twenty-two or fewer carbons, and A− is an anion.
A plastic composition comprising a halogen-containing plastic covalently bound to a sidechain, wherein the sidechain has a structure of:
- wherein m is an integer from 1-10, O is an integer from 1-10;
- X+ is a quaternized atom selected from a group consisting of nitrogen and phosphorous, wherein and R, R′ and R″ are independently selected alkyl, alkenyl or alkynyl groups, provided each has at least one carbon but twenty-two or fewer carbons, and A− is an anion.
