Provide the IUPAC name of the monomer(s) used to prepare the following polymer.  

What is the name given to polymers that soften when heated and harden when cooled?

Bonus question When an optically active D-aldopentose was subjected to Kiliani-Fischer synthesis, followed by NaBH4 / H2O, it produced a mixture of an optically active and an optically inactive alditol. When the same D-aldopentose was subjected to Wohl degradation followed by HNO3, it produced an optically inactive aldaric acid. Provide the name of this D-aldopentose.
