Which one of the following is NOT a copolymer?
Multiple Choice Options
- A Buna-S
- B Neoprene
- C PHBV
- D Butadiene-styrene
Step-by-Step Verified Solution
A copolymer is a polymer that consists of two or more different types of monomers.
Here are the options examined:
- Option A: Buna-S - It's a copolymer of butadiene and styrene.
- Option B: Neoprene - It is made from the polymerization of chloroprene, so it is a homopolymer, not a copolymer.
- Option C: PHBV - Polyhydroxybutyrate-co-valerate (PHBV) is a copolymer consisting of Polyhydroxybutyrate (PHB) and Polyhydroxyvalerate (PHV).
- Option D: Butadiene-styrene - This is another name for SBR, or styrene-butadiene rubber, and it's a copolymer of butadiene and styrene.
