Physico-mechanical properties of the products based on filled epoxy-oligomeric mixtures composed of Epidian-5 epoxy resin, oligoesteracrylate TGM-3 and monoperoxide derivative of Epidian-6 epoxy resin (PO) have been investigated. CaCO 3 was used as a filler and polyethylene polyamine was a curing agent. The effect of PO and CaCO 3 on the gel-fraction content and physicomechanical properties was examined. Using a scanning electron microscopy (SEM) the morphology of the samples has been studied.

Phenol-formaldehyde resins (PhFR) with reactive methacrylate fragments or labile peroxy bonds in the side branches used as a polymeric component of bitumen-polymeric mixtures have been investigated. Taking into account that PhFR with peroxy fragments based on epoxy resin does not described in literature, its synthesis procedure has been developed. The kinetic regularities of the reaction between peroxy derivative of epoxy resin (PDER) and phenol group of PhFR were studied taking the reaction of PDER with phenol as an example. The structure of PhFR with peroxy groups (PhFRP) has been confirmed by IR-studies. Bitumenpolymeric mixtures with PhFRP or PhFR with unsaturated fragments (PhFRU) in the amount of 1, 3, 5 or 7 mass parts per 100 g of petroleum bitumen were examined at 443, 463 or 483 K for 0.5, 1.0 or 2.0 h. The composition of bitumn-polymeric mixtures has been determined using the group analysis.

“…The reason is their advantages over other polymers such as easiness during products formation and good operational characteristics of the final products [6]. For many years the researches regarding the creation of ER based oligomers with various functional groups [7][8][9][10][11][12] have been conducted at Lviv Polytechnic National University (Ukraine).…”

Physico-chemical properties of developed nickel-containing modified silicate materials as the nucleators for composites based on polyamide 6 are presented. As it was established, additive of the nucleator modified by polyvinylpyrrolidone promotes the increase of crystallinity degree of polyamide 6 and the decrease of crystallite size. It was found that changes in the structure of the material cause the increase of its tensile strength, surface hardness and Vicat softening point.
