METHOD FOR MANUFACTURING A POLY(VINYL PHENOL) BY ESTER-EXCHANGING OF POLY(ACETOXY STYRENE) WITH AN ACID CATALYST |
| 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. |
