Polymerization and Uses of Polychloroethene and Polypropene

This video tutorial explains how to write equations for the formation of polychloroethene (PVC) and polypropene, detailing their polymerization processes and uses. It begins with a review of ethene polymerization, then covers chloroethene polymerization, highlighting PVC's applications in windows, doors, and pipes. The video also discusses polypropene, its structure, polymerization, and its uses in hinges, medical equipment, and containers.
