Reprocessable polymers and methods for the manufacture thereof

A polymer comprising repeating units derived from an ethylenically unsaturated monomer and a cyclic allyl sulfide, wherein the repeating units derived from the cyclic allyl sulfide are of the structure

• wherein R1 and R2 are independently at each occurrence hydrogen, a substituted or unsubstituted C1-6 alkyl group, a halogen, or R1 and R2 on a single carbon atom are taken together with the carbon atom to form a C═O.
