Which of the following polymers is an addition polymer formed by the free radical polymerization of vinyl chloride?
Show answer
Answer: B. Polyvinyl chloride (PVC)
Vinyl chloride (CH2=CHCl) undergoes addition polymerization through a free radical mechanism to form polyvinyl chloride (PVC). Nylon-6,6 is a condensation polymer, Bakelite is a thermosetting polymer formed from phenol and formaldehyde, and Dacron is a polyester formed from ethylene glycol and terephthalic acid.
Which synthetic polymer is commonly used in non-stick cookware coatings?
Show answer
Answer: C. Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon, is known for its non-stick properties and is widely used in cookware coatings.
What are the repeating units in polyacrylonitrile, commonly used in acrylic fibers?
Show answer
Answer: A. CH2=CH-CN
Polyacrylonitrile is formed by the addition polymerization of acrylonitrile, whose chemical formula is CH2=CH-CN. The repeating unit in the polymer is -[CH2-CH(CN)]-.
The polymer formed by the ring-opening polymerization of lactams is a type of:
Show answer
Answer: C. Polyamide
Lactams are cyclic amides. When they undergo ring-opening polymerization, they form polyamides, with Nylon-6 being a prime example derived from caprolactam.
The reaction of diisocyanates with polyols produces which type of polymer?
Show answer
Answer: C. Polyurethane
Polyurethanes are formed by the reaction of diisocyanates (e.g., toluene diisocyanate, TDI) with polyols (compounds with multiple hydroxyl groups).
