| titleOfInvention | Process and composition for the manufacture of epoxy-resins |
| abstract | A process for the manufacture of substantially linear 1:2-epoxy resins comprises reacting an epoxide compound having an epoxy equivalency greater than 1 of molecular weight 250 to 1,000 with a dihydric phenol in the presence, as a catalyst, of lithium hydroxide in a proportion amounting to less than 0,006% based on the weight of the dihydric phenol. Specified epoxy starting materials are methyl-9:10:12:13-diepoxy stearate, the dimethyl ester of 6:7:10:11-diepoxyhexadecane-1:16-dicarboxylic acid; diethylene glycol bis-(3:4-epoxycyclohexane carboxylate), 3:4 - epoxy - 6 - methylcyclohexylmethyl - 3:4-epoxy-cyclohexane carboxylate, diglycidyl esters of which many are specified and diglycidyl ethers of glycols and dihydric phenols of which many are specified. The examples describe the preparation of epoxy resins, in the presence of lithium hydroxide monohydrate from:- (1) to (7) a bis-phenol-A-epichlorohydrin condensate and bis-phenol-A; (8) a bis-ortho-cresol-epichlorohydrin condensate and bis-ortho-cresol; (9) 3,4 - epoxy - 6 - methylcyclohexylmethyl - 3,4-epoxycyclohexane carboxylate and bis-phenol-A; (10) 3,4 - epoxy - 6 - methylcyclohexylmethyl - 3,4-epoxycyclohexane carboxylate and resorcinol; (11) a polypropylene glycol-epichlorohydrin condensate and resorcinol and (12) butane diol diglycidyl ether and bis-phenol-A. |
