It has been shown that the chlorine-containing unconjugated enyne alcohols react with epichlorohydrin in the presence of boron trifluoride etherate with formation of chlorohydrines, which further without their isolation, under the action of potassium hydrochloride are dehydrochlorinated with formation of the corresponding glycidyl ethers. Under the action of an alcoholic solution of potassium hydroxide at temperature of 75-80 °С on synthesized chlorine-containing ethers the dehydrochlorination reaction on double С=С bond proceeds and glycidyl ethers of 1,4-diine series are formed. It has been revealed that the synthesized glycidyl ethers are the very reactive compounds. In patricular, it has been shown that the ethers of 1,4-diine series with the participation of oxirane ring undergo the reaction with thiurea medium of methanol at 30-35 °С, forming the corresponding tyrants. The data of IR- and NMR-spectra of the prepared compounds have been presented and their modifying properties in relation to phenol-formaldehyde oligomers in acidic and alkaline media have been revealed. The prepared modified oligomers are the products of liquid-viscous consistency, soluble in acetone, tetrahydrofuran, dimethyl formamide and dioxane. It has been proved by the carried out analyses that the prepared PhFOs, modified by glycidyl and thiglycidyl ethers of diacetylene series are not mechanical mixtures of phenol, formaldehyde and modifier. On the basis of obtained results the formation mechanism of modified resol and novolac PhFO has been also revealed. It has been established that the physical-chemical and physical-mechanical parameters of the prepared phenol-formaldehyde oligomers modified by modifiers proposed by us, in comparison with unmodified ones, are improved. From the proposed diglycidyl and thiodiglycidyl ethers for the modification of PhFO the best results on all parameters are achieved at modification with thioglycidyl ether of diacetylene series.

The method of synthesis of epoxy compounds containing silicon on basis of hydrosilylation reaction of allyl derivatives of glycidyl ethers with methyl diethyl silane in the presence of platinum-hydrochloric acid was developed. It was determined that these silanes enter into the reaction with various agents bound with oxirane ring by forming corresponding derivatives of organosilicon compounds. Twelve synthesized organosilicon compounds were used as coupling agents for quartz nanoparticles. It was determined that synthesized organosilicon compounds have good coupling agents promoting improvement of compatibility of mineral filler with polymeric matrix. Quartz nanoparticles (up to 100 nanometers) were used as mineral filler. Nanoparticles quartz received on analytical mill А-11 at speed of rotation of a rotor of 28000 turn/min. The dimension of nanoparticles was defined on the device of model STA PT1600 Linseiz Germany and compounded 20-100 nm. For research of physical-mechanical properties of the polymerous nano composites they subjected to pressing at temperature of 190-200 °С. From the pressed plates samples for definition of breaking stress, specific elongation, flexural strength of the filled composites cut down. Research results of influence of type and concentration of coupling agent and filler upon main physical-mechanical properties of nanocomposites are given. Dressing nanoparticles carried out in 0.5 - 2.0 % water solution of the silicoorganic compound acidified by acetic acid to рН = 3.5, at temperature of 55 °С in flow during 60 min. Optimal concentrations of coupling agents and filler, which provide maximal values of composites physical-mechanical properties, were determined. Main reasons providing improvement of strength properties of finished nanocomposites were revealed. The comparative analysis of the data obtained shows that rather high physical-mechanical properties possess nanocomposites in which as dressing 2-metil-5-metildietylsilil-2- (methylenoxy-1,3-dioxosolano) – pentane was used.Forcitation:Gurbanova R.V., Kakhramanov N.T., Shatirova М.I., Мuzafarov А.М., Kahramanly Yu.N., Mammadli U.M.
