Polymers containing aromatic dicarboxylic acid
A process is provided for making a polymer comprising providing a mixture of at least one furandicarboxylic acid, at least one diol, and at least one C2-C3 dicarboxlic acid, ester derivatives of C2-C3 dicarboxylic acid, hydroxy fatty acid or ester derivative of a hydroxy fatty acid; adding a catalyst and processing said mixture at reaction conditions until a polymer product is produced. The polymer consists of random units based upon the starting materials that are used.
