The article discusses the study which examines the impact of ozone in plane stress state of polyurethanes. The study tests polydiene urethane (PDU) composites from Krasol-grade oligomers of various molecular weight M, PDI-1K (divinylisoprene), and hydroxyl containing oligomer SKDP-N (divinylpiperylene) through optical microscopy and infrared (IR) fourier spectroscopy. Result shows that polyurethanes' ozone sensitivity depends on molecular weight characteristics (MWCs).

The article focuses on the study regarding the possibility of polymer composite modification based on nitrile butadiene rubber containing 2-cis-septodecylbenzimidazole and 2-abietinatebenzimidazole. The study assessed the vulcanisation characteristics of the rubber mixes based on the results of a test conducted using a Monsanto 100 instrument. The study showed that vulcanisates produced with benzimidazole derivatives have increased mechanical properties.

The article discusses the elastomer composites of vulcanising systems to improve the properties of butadiene-acrylonitrile rubber with 2-styrylbenzimidazole (2-SBA). It investigates the modification of rubber mixes with benzimidazole which is of definite interest. In addition, the synthesis of 2-SBA was conducted with account taken of the results of preliminary investigation of reaction mixes on a Paulik-Paulik-Erdei derivatograph in quasi-isothermal mode.
