Plasticisers are added to synthetic plastics to ________________?
Correct answer: D. All A., B. and C.
- A. Impart flexibility
- B. Improve workability during fabrication
- C. Develop new improved properties not present in the original resin
- D. All A., B. and C.
Explanation
Plasticisers lower intermolecular forces in a polymer, increasing flexibility and making fabrication easier. They may also provide other performance improvements, so all three listed effects are included.
