Abstract

Official abstract text for this publication.

In an example, a process of forming a polymeric material is disclosed. The process may include chemically reacting a polyvinyl chloride (PVC) material with a diamine to form a diamine-modified PVC material. The diamine has a chemical formula (CH 2 ) x (NH 2 ) 2 , where x is not less than 2. The process may also include chemically reacting a halogenated phthalate plasticizer with the diamine-modified PVC material to form a polymeric material having a phthalate plasticizer covalently bonded to a polymer chain.

First claim

Opening claim text (preview).

The invention claimed is: 1. A process of forming a polymeric material, the process comprising: chemically reacting a polyvinyl chloride (PVC) material with a diamine having a chemical formula (CH 2 ) x (NH 2 ) 2 to form a diamine-modified PVC material, wherein x is not less than 2; and chemically reacting a halogenated phthalate plasticizer with the diamine-modified PVC material to form a polymeric material having a phthalate plasticizer covalently bonded to a polymer chain. 2. The process of claim 1 , wherein the PVC material includes a chlorinated PVC (CPVC) material. 3. The process of claim 1 , wherein the diamine includes ethylene diamine. 4. The process of claim 1 , wherein the halogenated phthalate plasticizer includes a brominated phthalate. 5. The process of claim 4 , wherein the brominated phthalate includes 4-bromophthalic anhydride. 6. The process of claim 1 , further comprising chemically reacting a halogenated phthalate with an alcohol to form the halogenated phthalate plasticizer. 7. The process of claim 6 , wherein the alcohol includes an aliphatic alcohol. 8. The process of claim 7 , wherein the aliphatic alcohol includes isononyl alcohol. 9. The process of claim 8 , wherein the halogenated phthalate plasticizer includes brominated diisononyl phthalate (DINP). 10. The process of claim 7 , wherein the aliphatic alcohol includes isoheptyl alcohol. 11. The process of claim 10 , wherein the halogenated phthalate plasticizer includes brominated diisoheptyl phthalate (DIHP). 12. A polymeric material having a phthalate plasticizer covalently bonded to a diamine-modified portion of a polyvinyl chloride (PVC) polymer chain, wherein the PVC polymer chain is modified using an aliphatic diamine having a chemical formula (CH 2 ) x (NH 2 ) 2 , wherein x is not less than 2. 13. The polymeric material of claim 12 , wherein the phthalate plasticizer includes diisononyl phthalate (DINP). 14. The polymeric material of claim 12 , wherein the phthalate plasticizer includes diisoheptyl phthalate (DIHP). 15. The polymeric material of claim 12 , wherein the aliphatic diamine includes ethylene diamine. 16. A polymeric material formed by a process comprising: chemically reacting a chlorinated polyvinyl chloride (CPVC) material with an aliphatic diamine having a chemical formula (CH 2 ) x (NH 2 ) 2 to form a diamine-modified CPVC material, wherein x is not less than 2; and chemically reacting a halogenated phthalate plasticizer with the diamine-modified CPVC material to form a polymeric material having a phthalate plasticizer covalently bonded to a polymer chain. 17. The polymeric material of claim 16 , wherein the halogenated phthalate plasticizer includes a brominated phthalate plasticizer. 18. The polymeric material of claim 17 , wherein the brominated phthalate plasticizer includes brominated diisononyl phthalate (DINP). 19. The polymeric material of claim 17 , wherein the brominated phthalate plasticizer includes brominated diisoheptyl phthalate (DIHP). 20. The polymeric material of claim 16 , wherein the aliphatic diamine includes ethylene diamine.
