Synthesis Mechanism and Properties of Epoxy Resins Modified with Adipic Acid

Abstract

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.

Influence of Modified Epoxy Resins on Peroxide Curing, Mechanical Properties and Adhesion of SBR, NBR and XNBR to Silver Wires—Part II: Application of Carboxy-Containing Peroxy Oligomer (CPO)

“…Thirty grams (30 g) of monoperoxy derivative of epoxy resin (PO) [ 2 ] dissolved in 150 mL of isopropanol, 3.7 g of benzyl triethylammonium chloride dissolved in 3.3 mL of water and 12.0 g of adipic acid dissolved in 50 mL of isopropanol were placed in the reactor. The reaction mass was sustained at 60 °C under stirring for 20 h. Then, 150 mL of toluene was added, and the mixture was carried into the dividing funnel.…”

“…The current state of knowledge on how to improve adhesion between polymer and metals was described in the first part of our work [ 1 ]. It was devoted to epoxy resin containing peroxide group (PO) [ 2 ], whereas the second part of the paper deals with carboxy-containing peroxy oligomer (CPO) [ 3 ]. The aim of the study was similar—to determine the effect, this time of CPO addition, on the mechanical properties of selected synthetic rubbers and their adhesion to silver.…”

Influence of Modified Epoxy Resins on Peroxide Curing, Mechanical Properties and Adhesion of SBR, NBR and XNBR to Silver Wires. Part I: Application of Monoperoxy Derivative of Epoxy Resin (PO)

“…For composites containing metallic phases, it becomes crucial to ensure proper adhesion between the continuous and dispersed phases, which can be helped by adding proadhesive systems in the form of modified resins to polymer matrix [ 1 ]. The aim of the study was to determine the effect of the addition of epoxy resin containing peroxide group (PO) [ 2 ], synthesized previously, on mechanical properties of some synthetic rubbers and their adhesion to silver. Silver wires have been selected as a tester to check the proadhesive potential of the important technical rubbers: styrene-butadiene (SBR), acrylonitrile-butadiene (NBR) and carboxylated acrylonitrile-butadiene (XNBR), to silver nanofillers.…”

Obtaining of Coumarone-Indene Resins Based on Light Fraction of Coal Tar. 2. Coumarone-Indene Resins with Epoxy Groups

“…Last decade a series of researches has been carried out in Lviv Polytechnic National University regarding the usage of industrial wastes for the production of new polymeric compounds [3][4][5][6][7][8][9][10][11][12]. These wastes contain different by nature monomers capable of creating new polymeric compounds under certain conditions.…”

“…For instance, the so called C9 fraction is obtained after rectification of the product obtained during hydrocarbons pyrolysis to ethylene [3,4]. The C9 fraction contains 40-70 % of unsaturated compounds; it is successfully used for the production of petroleum resins [3][4][5][6][7][8][9][10][11][12]. The introduction of functional groups, namely epoxy [5], carboxy [9], hydroxy [14] and other groups [12] into the resin structure allows to use the resins as additives when producing protective coatings [13], bitumen-polymeric mixtures [15] and different materials [16].…”
