Synthetic Polymer. Synthetic polymers are an attractive class of materials due to the ability to tailor the material properties for specific applications such as altering the molecular weight or chemistry to influence degradation or mechanical properties (Kohane and Langer, 2008; Guo and Ma, 2014). Like all synthetic polymers, they can be synthesized at reproducible quality and purity and fabricated into various shapes with desired bulk and surface properties. Specific advantages include the

Addition vs. condensation polymers. A polymer is a very large molecule that is built from monomers (the repeating units that make up a polymer). Many different biomolecules, such as DNA, proteins, and carbohydrates , are polymers.

A polymer is analogous to a necklace made from many small beads (monomers). A chemical reaction forming polymers from monomers is called polymerization, of which there are many types. A common name for many synthetic polymer materials is plastic, which comes from the Greek word "plastikos", suitable for molding or shaping. Addition vs. condensation polymers.
