Claims14
A polymer comprising:
- a plurality of repeated polymerized units according to scheme (2):
A method of making a polymer comprising:
- dimerizing trans-cinnamic acid, forming CBDA-1;
- reducing CBDA-1, forming CBDO-1;
- condensing CBDO-1 with a diacid, forming monomeric subunits;
- and
- polymerizing the monomeric subunits together to form the polymer.
