METHOD OF MAKING A PARTICULATE EPOXY RESIN |
摘要 |
A method of making an epoxy resin by condensing a polyphenol and a compound selected from epichlorohydrin, 1,3-dichloro-2-propanol, and homologs thereof in water that is free of added organic solvent at an elevated temperature and in the presence of a catalyst. The method comprises carrying out the condensation in the presence of a dispersion promoting agent whose solubility in water decreases with increasing temperature. |
