Abstract
The present disclosure relates to polymers, methods for polymer synthesis, and methods of modifying the backbone of said polymers. Modification of the polymer backbone via a sigmatropic rearrangement allows facile entry into new, highly ordered polymers.
Claims13
A method of preparing a product polymer, the method comprising:
- (a) obtaining a polymer, wherein the backbone of the polymer comprises at least one (a) sigmatropomer repeat unit of Formula I, II, or III:
- wherein R1, R2, and R3, are, in each instance, independently selected from hydrogen and alkyl;
- R4 is, in each instance, selected from hydrogen, alkyl, and hydroxyl;
- and
- R5 is, in each instance, selected from hydrogen, alkyl, and aryl;
- and
- (b) inducing a sigmatropic rearrangement of the sigmatropomer in the backbone of the polymer, thereby producing the product polymer.
