PROCESS FOR THE PREPARATION OF A POLYETHER RESIN Process for the preparation of a polyether resin by reacting a diglycidyl ether of a dihydric phenol with an alcohol of formula R-C(CH2OH)3, R being C1-5-alkyl, using an equivalent ratio eOH to eepoxy > 1 and selecting P > 1.05, wherein (1) Fepoxy being the epoxy functionality of the diglycidyl ether. By the process of the invention polyester resins can be obtained at A relatively low temperature and which are substantially free from epoxy groups without a gel being formed. Moreover, cured films prepared from polyether resins so obtained have very good properties in can and general industrial stoving application, for example a very good sterilization resistance, salt spray resistance and very goad flexibility. |
