Effect of Hydrodynamic Motion Mode of the Reaction Mixture on the Thermomechanical Properties of Copolymers of Butadiene and Isoprene – Zakharov V.P., Mingaleev V.Z., Zakharova E.M., Zakirova I.D. (P 8 )

Method of copolymerization of butadiene and isoprene in presence of a titanium catalyst system at formation of the reaction mixture in pre-reactor tube of turbulent confuser-diffuser design is suggested. Presence of turbulence results in the change of microstructure of copolymer. As a result both glass transition temperature and temperature of flow of copolymers of 20% and 40% butadiene content became lower in average on 14 and 9○C respectively.

Key words: butadiene, isoprene, copolymerization, titanium catalyst, glass transition temperature, flow temperature

Modeling of the Kinetics of Evaporation of a Mixture of Flame Retardants from Rubber – Dedov A.V., Nazarov V.G. (P. 54)

Efficiency of the application of the well-known model for forecasting of evaporation of a mixture of flame retardants in rubber has been studied. The model is designed to predict the rate of evaporation, determined by the diffusion of ingredients in rubber.
