Electrical conductivity of semiconductor pyropolymers in an alternating electrical field

Multifunctional ingredients for composite elastomer materials

“…And the use of a sulfur vulcanizing system activates the vulcanization min process, which is facilitated by the presence of active functional groups (-OH, -COOH, etc.) in its composition [8][9][10]. The observed effect is confirmed by IR studies of the reaction products of furan oligomers and thiuram at elevated temperature.…”

“…The higher the frequency, i.e. the shorter the exposure time, the higher will be the glass transition temperature of the plasticized system [1][2][3][4][5][6][7][8][9][10][11][12][13].  OFF-oligomer from furfural, OTHFS-oligomer of tetrahydrofurfuryl alcohol, OFFSoligomer from furfuryl alcohol.…”

“…10-4 s-1 for technical rubber, which indicates its great influence on side reactions to inhibit the oxidation of elastomers. Studies of the thermal aging of composites stabilized with furan oligomers have shown that with an increase in the duration of aging time, a decrease in the relative elongation of the composites is observed, compared with samples stabilized with neazone D. Apparently, in the process of thermal exposure under the action of furan units, additional structuring occurs due to which leads to an increase in rigidity and a decrease in the values of relative elongation of composites [9][10][11][12][13][14][15].…”

Gas pyrolysis resin as a plasticizer for composite elastomer materials

“…Simultaneously with an increase in the strength of composites (by 13-17%), there is a decrease in elasticity, residual elongation, and an increase in rigidity. This circumstance can be explained by an increase in the degree of crosslinking and the introduction of P 125 into the composition, which lead to a deterioration in the flexibility of elastomer macromolecules [10,11]. The equilibrium swelling of vulcanizates with respect to machine oil, gasoline, kerosene, etc.…”
