2. Discuss 3 safety considerations for our laboratory today.
1. UV light
2. MMA should be used in a hood
3. MMA required use of gloves
3. What is the key difference between photopolymerization and thermally-initiated vinyl
polymerization?
In thermal polymerization, the initiating radicals are formed from the thermal
cleavage of a bond. In UV curing, the bond is broken via light excitation whereby
the excited species dissociates to form the radicals.
4. From what journal did today’s literature come from?
Langmuir
