Step-by-step explanation:
Some polymers are flexible. Others are very stiff. Just think of the many types of plastics: The material in a flexible soda bottle is very different from that in a rigid pipe made from polyvinyl chloride (PVC). Sometimes materials scientists add other things to their polymers to make them flexible. Known as plasticizers (PLAA-stih-sy-zurs), these take up space between individual polymer chains. Think of them as acting like a molecular-scale lubricant. They let the individual chains slide across each other more easily.
