Polymerization of butadiene under the action of n-butyl lithium modifi ed by of alkali and alkaline earth metal alkoxides was researched. Microstructure and molecular characteristics of the samples of polybutadiene synthesized were determined. The infl uence of polymerization conditions on the properties of the resulting polymer was examined.

New acid corrosion inhibitor OPC-2000 has been developed for a single stage process of isoprene synthesis. Gravimetric method has found high effectiveness of the inhibitor in conditions of dilute ortho-phosphoric and sulfuric acids towards alloys Incoloy 825 and 12X18H10T being applied within the range of 10-16 g/dm3. According to electrochemical investigation, OPC- 2000 is an anodic class inhibitor. It has high dispersing properties (no sediment formation in reactors), the fact being confirmed in the course of PJSC Nizhnekamsneftekhim’s industrial trials while a single stage of isoprene synthesis.
