PROCESS FOR THE PREPARATION OF POLY(VINYLPHENOL) FROM POLY(ACETOXYSTYRENE) BY ACID CATALYZED TRANSESTERIFICATION |
| 摘要 |
Polymers of 4-vinylphenol are made by the acid catalyzed transesterification of polymers of 4-acetoxystyrene in an alcohol. The 4-vinylphenol polymers are useful as epoxy resins curing agents and as the phenolic base for epoxy resin per se. B:3.P-126 |
