A bio-polyester is synthesized for use in biodegradable medical sutures. The structure of the repeating unit of this polymer is shown below:
What type of polymerisation reaction takes place to form this polymer from its monomers, and what is the small molecule released as a byproduct?
Addition polymerisation; no small molecule is released.
Condensation polymerisation; water (H2O\text{H}_2\text{O}H2O) is released.
Condensation polymerisation; hydrogen chloride (HCl\text{HCl}HCl) is released.
Addition polymerisation; water (H2O\text{H}_2\text{O}H2O) is released.
