Various N435 loadings were screened to assess the stability of HEAA. HEMA is included as a positive control as it is known to react with itself in the presence of N435.
| N435 loading (wt% w.r.t initiator) | Transesterification of HEMA after 20 ha (%) | Self-reaction of HEAA after 20 ha (%) |
|---|---|---|
| 5 | 25 | Not detectable |
| 10 | 29 | Not detectable |
| 20 | 41 | Not detectable |
Determined by 1H-NMR.
