[2025-09-30T12:24:01.193279] [PI reasoning] **Considering dental polymerization**

I need to answer a question about acrylic resin polymerization, focusing on benzoyl peroxide and its role in generating free radicals. For cold-cure resins, tertiary amines speed up the reaction at room temperature. Without an activator, I remember that thermal activation begins at about 60°C. So, my answer should be 60°C, as benzoyl peroxide decomposes around this temperature. I’ll definitely need to support this with references from dental materials textbooks.
