| abstract | 1,210,045. Epoxy resin esters. SOC ITALIANA RESINE S.p.A. 24 June, 1969 [15 July, 1968], No. 31924/69. Heading C3B. Epoxy resins having an epoxide equivalent of 180-3500 and which contain hydroxyl groups in the molecule are esterified while leaving the epoxy groups substantially intact. The resins are reacted with a methyl, ethyl, propyl or butyl ester of a saturated or unsaturated fatty acid, said acid containing up to 20 carbon atoms in the presence of a catalyst which is an alkali metal or alkaline earth metal salt of an organic acid having an acid dissociation constant, or in the case of a polybasic acid, a first dissociation constant <20 Î 10<SP>-5</SP>, at 160-230‹ C.; reaction is continued until substantially none of the fatty acid ester remains. Th catalyst may be used at 0À0005 to 0À2 parts by wt. per 100 parts by wt. of the reacting mixture. Examples of catalysts are calcium acetate, lithium ricinoleate and lithium carbonate. The fatty acid ester used in the examples was methyl oleate. |
