Epoxy resins (i.e., epoxide polymers) ?
Correct answer: B. Contain an epoxy group (fig bellow) at the ends of the polymer
- A. Are made by addition polymerisation reaction only
- B. Contain an epoxy group (fig bellow) at the ends of the polymer
- C. Are cross-linked polymers only
- D. Use emulsion polymerisation methods
Explanation
Epoxy resins are commonly made from molecules such as diglycidyl ethers that retain terminal epoxy groups, which later react with curing agents to form a network. They are not restricted to addition polymerisation or emulsion methods, and the uncured resin is not necessarily cross-linked.
