| Monomer or component of the polymerization initiator system | Acronym | Mass% |
|
|---|---|---|---|
| LC | DCa | ||
| Urethane dimethacrylate | UDMA | 48.7 | 47.2 |
| Poly(ethyleneglycol)-extended UDMA | PEG-U | 30.0 | 29.1 |
| 2-hydroxyethyl methacrylate | HEMA | 17.3 | 16.8 |
| Methacryloyloxyethyl phthalate | MEP | 3.0 | 2.9 |
| Camphorquinone | CQ | 0.2 | – |
| Ethyl-4-N,N-dimethylamino benzoate | 4EDMAB | 0.8 | – |
| Bis(2,6-dimethoxynezoyl)-2,4,4-triethylpentyl | 1850 IRGACURE | – | 1.0 |
| Phosphine oxide & 1-hydroxycyclohexyl phenyl ketone benzoyl peroxide | BPO | – | 2.0 |
| 2,2′-dihydroxyethyl-p-toluidine | DHEPT | – | 1.0 |
a
DC resin was fabricated by mixing equal amounts by mass of the UPHM resin containing 1850 IRGACURE and BPO with the UPHM resin containing DHEPT
