摘要：

A phase-separated epoxy blend containing a sulfonium salt cationic photoinitiator was studied. The onium salt was found to be preferentially soluble in one of the resins of the system. Scanning electron microscopy and microprobe analyses were done to determine the concentration distribution in the phases and the results compared to a model based on liquid extraction distribution coefficient behavior. Finally, the photolithographic behavior of various blends of the epoxy resins is discussed and the results compared to the behavior predicted by the photoinitiator distribution.
