Chemical Modification of ED-24 Epoxy Resin Peroxy Derivative by C9H4F16O Fluorine-Containing Alcohol-Telomer

The main regularities of the modification with a rubber crumb for bitumen produced from the residuals of crude oils of Ukrainian deposits have been studied. The thermal stability of the rubber crumb has been examined using the derivatograpgy. The mechanism of bitumen modification with the rubber crumb at low and high temperatures has been established. The influence of technological factors on the main quality indices of modified bitumen has been studied. The changes in the group composition of the original and modified bitumen were found.

“…Modification of epoxy oligomers improves their properties and expands the areas of their practical application. Alcohols [5,7], phenols [5,8], acids [5,9,10], acid anhydrides [11] and others [12,13]) are among low-molecular compounds for epoxy oligomers modification.…”

The mechanism of diepoxide and adipic acid (AA) reaction in the presence of benzyltriethylammonium chloride and 1,4-diazobicyclo[2,2,2] octane has been proposed. The thermal stability of the oligoester obtained via chemical modification of the dioxydiphenylpropane diglycidyl ether with AA and epoxy-oligoesteric mixtures with its participation has been studied. The viscoelastic properties of films based on epoxy-oligoesteric mixtures containing Epidian-5 epoxy resin, TGM-3 oligoesteracrylate, AA modified Epidian-5 and polyethylpolyamine have been determined.

Cross-linking of epoxy-oligomeric mixtures based on ED-20 industrial epoxy dianic resin and TGM-3 oligoesteracrylate in the presence of fluorine-containing peroxy oligomers has been studied. Oligomers used for the cross-linking have been obtained via chemical modification of peroxy derivative of ED-24 epoxy resin with alcoholstelomers by general formula HOCH 2 -(CF 2 -CF 2 ) n H, where n is 3 or 4. The thermal stability of peroxy groups in the initial material, fluorine-containing peroxy oligomers and stability of cross-linked films have been examined using derivatographic methods. The effect of temperature, process time and mixture composition on the gel-fraction content and hardness of obtained films has been established.
