Which polymer is described as a colorless, non-toxic resin with a characteristic odor, primarily used as an adhesive?
Correct answer: B. Polyvinyl Acetate (PVA)
- A. Polystyrene
- B. Polyvinyl Acetate (PVA)
- C. Polyvinyl Chloride (PVC)
- D. Polyamide
Explanation
The correct answer is Polyvinyl Acetate (PVA). PVA is a colorless, non-toxic resin with a distinct odor and is primarily used as an adhesive, especially in products like wood glue and school glue. The other options are not primarily used as adhesives: Polystyrene is used for insulation and packaging, PVC is used in construction materials, and Polyamide is utilized in textiles and engineering components.
