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

Abstract

1 Coumarone-indene resins with epoxy groups (CIRE) have been obtained using light fraction of coal tar or fraction with the distillation range of 423-463 K based on it. Styrene and glycidyl methacrylate were used as modifiers. CIRE were synthesized via radical cooligomerization using monoperoxide derivative of dioxyphenylpropane diglycidyl ether (PO) as an initiator. Thermal stability of PO has been studied. The effect of initiator amount, reaction temperature and time on the yield and softening temperature of CIRE has been determined. The structure of the synthesized CIRE was confirmed by IR and 1 H NMR spectroscopy.

Obtaining of Coumarone-Indene Resins Based on Light Fraction of Coal Tar. 3. Coumarone-Indene Resins with Methacrylic Fragments

“…The studied LFCT and ICF contain indene, coumarone and styrene [21].Under certain conditions they are capable of cooligomerization and formation of coumarone indene resins. At the same time, it is evident that concentration of such compounds is low, which requires the addition of styrene to the initial mixture to increase the yield of resins [21,22].…”

“…Both fractions contain sufficient amounts of indene, coumarone, styrene and other unsaturated compounds, and therefore they are used to produce the so-called coumarone-indene resins (CIR) which may be used as polymer components for the creation of bitumen-polymer mixtures [20]. CIR with functional groups, namely epoxy and carboxy groups, are described by M. Bratychak et al [21,22]. Functional groups in the CIR structure increase the adhesion properties of the final products.…”

“…4 These byproducts, in particular the light fraction, containing indene, coumarone, styrene and other hydrocarbons. This made it possible to create on its basis the indenecoumarone resins with carboxy, 4 epoxy, 20,21 and methacrylate 22 groups. The synthesized indene-coumarone resins with functional groups are used as active additives to improve the properties of petroleum bitumen.…”

Obtaining of Coumarone-Indene Resins based on Light Fraction of Coal Tar. 5. Emulsions on the Basis of Bitumen Modified by Coumarone-Indene Resins with Epoxy Groups

“…Recently, at the Department of Chemical Technology of Oil and Gas Processing at Lviv Polytechnic National University, new bitumen modifiers have been developed based on petroleum [11][12][13], phenolformaldehyde [14][15][16], epoxy [16] and coumarone-indene resins without [17][18] and with functional groups [19][20][21][22]. The most promising results were obtained for coumarone-indene resins with functional groups, since they are produced from a light fraction of coal tar, which is available and low cost by-product of coal coking.…”
