Synthesis and characterization of petroleum resins with epoxy groups

Synthesis and characterization of some degradable polyesters

“…This behavior was found to run in harmony with the explanation given by Banno [20]. A similar explanation has been proposed by Bratychak et al [21][22][23][24][25][26]: a satisfactory cure was achieved by degradation of peroxy groups, of peroxy urea-formaldehyde oligomers, to form The variations of T max and t max with the CO concentration show that the maximum value of T max is attained when about 0.02 wt % CO is used. The addition of more accelerators raises T max slightly.…”

Effects of Hydrophilic Silica Nanoparticles on Morphology and Mechanical Properties of a Typical Tyre Compound

“…[2][3][4] In order to extend the application area of PPR, especially for the creation of various composite materials, the researchers of Lviv Polytechnic National University have conducted studies on improving the PPR functionality. [6][7][8][9] For this purpose, PPR with epoxy, 6, 10-14 carboxy, 7,[15][16][17][18] and hydroxy 8,19 groups were synthesized.…”

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

“…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].…”
