During polymerisation of acrylic resin, above what temperature benzoyl peroxide form freeradicals_______________?
Correct answer: D. 60°C
- A. 25°C
- B. 37°C
- C. 50°C
- D. 60°C
Explanation
Benzoyl peroxide in heat-cured acrylic resin decomposes sufficiently to generate free radicals at approximately 60°C or above. These radicals initiate addition polymerization of methyl methacrylate.
