Abstract
Disclosed are methods for upcycling polyvinyl chloride (PVC) that involve the dissolving of PVC in an organic solvent; and contacting the PVC with a base, thereby providing a partially dehydrochlorinated PVC. Polymers made by the disclosed, and articles therefore, are also disclosed.
Claims23
A partially hydrogenated, dehydrochlorinated PVC having the structure
- wherein x is from 1 to 100,000, y is from 0 to 100,000, w is from 1 to 100,000, and z is from 2 to 100,000.
A method of partially dehydrochlorinating polyvinylchloride (PVC), comprising:
- dissolving the PVC in an organic solvent;
- and contacting the PVC with a base, thereby providing a partially dehydrochlorinated PVC.
