Polyvinyl chloride (PVC) is the correct answer because it is an addition polymer formed through the polymerization of vinyl chloride monomers without the loss of any small molecules. In contrast, nylon 6,6 and nylon 6,10 are both condensation polymers, as they are created through condensation reactions that release water during the process. Polyester is similarly a condensation polymer, formed from the reaction of diols and dicarboxylic acids, also releasing small molecules. Therefore, the only addition polymer in this list is polyvinyl chloride.

Polyvinyl chloride (PVC) is an addition polymer made from the polymerization of vinyl chloride monomers. It is widely used in construction and plumbing.

Nylon 6,6 is a condensation polymer formed from the reaction of hexamethylenediamine and adipic acid, resulting in the release of water molecules during the polymerization process.

Nylon 6,10 is also a condensation polymer, synthesized from the reaction of hexamethylenediamine and sebacic acid, which similarly releases water during polymerization.

Polyester is typically a condensation polymer formed from the reaction of diols and dicarboxylic acids, resulting in the loss of small molecules like water or methanol.
