Decomposition Products
Another parameter to consider for selection of organic peroxide for polymerization initiation is the nature of the decomposition products. These decomposition products may remain in the polymer, resulting in undesirable properties such as:
- Poor organoleptic performances
- Yellowing
- Low weathering performances
| Peroxide family |
Main decomposition products |
Peroxyesters
 |
CO2, carboxylic acids, acetone, alkanes, tButyl alcohol |
Diacyl peroxides
 |
CO2, carboxylic acids, alkanes |
Peroxydicarbonates
 |
CO2, alcohols |
Monoperoxycarbonates
 |
CO2, alcohols, acetone, alkanes |
Peroxyketals
 |
CO2, tButyl alcohol, acetone, alkanes, cyclohexanones |
Dialkyl peroxides
 |
alcohols, ketones, alkanes |
Hydroperoxides
 |
ketones, alcohols, alkanes |
The table above shows the main decomposition products of major peroxide families.
