Polymers Of Chloroethene & Propene

The video tutorial covers the formation and uses of polychloroethene (PVC) and polypropene. It begins with a review of ethene polymerization, explaining how double bonds break under pressure to form long-chain polymers. The tutorial then details the polymerization of chloroethene into PVC, highlighting its applications in windows, doors, and pipes. Next, it discusses polypropene, emphasizing its strength and resistance to fatigue and temperature, making it suitable for hinges, medical equipment, and kitchenware. The video concludes with a recap of the polymerization processes and their practical uses.
