Activating Mixing in Modification of Rubbers in Solution

The applicability of the previously developed principles of activating mixing to modification of rubbers in solutions was tested, and a process was developed for mechanochemical modification of cis-1,4-polyisoprene in rotary pulsation apparatus.     

Preparation of Compounds of Epoxy Resins with Low-Molecular-Weight Carboxyl-containing Rubbers by Activating Mixing

A process was developed for preparing adhesives from a low-molecular-weight carboxyl-containing rubber and an epoxy resin with different oligomer ratios. The process involves the chemical reaction of the components under conditions of activating mixing.     

Catalyst for Melamine Production

A novel electrolytic method for preparing the catalyst (active aluminum oxide) for melamine synthesis and a process for catalytic synthesis of melamine from urea are proposed.     

Activating Mixing in Preparation and Modification of Polymeric Composites

The concept of activating mixing as a procedure for preparing and modification of polymeric composites was developed. A new classification and generalized parameters of mixing, characterizing conditions of the energy supply to polymeric composition through the device working elements, were proposed. The dependence for determining the treatment modes providing controllable development of chemical transformations in a polymer system, which is invariant with respect to treatment modes and working installation, was obtained.     

Preparation and modification of low-viscous polymeric composites in rotary-pulsatory apparatus in the self-oscillating mode

Preparation and modification of low-viscous polymeric composites in rotary-pulsatory apparatus operating in the self-oscillating mode are described. These are synthesis of antioxidant dispersions, preparation of artificial latexes from an isoprene rubber, modification of epoxy resins with low-molecular-weight carboxyl-containing rubbers, modification of cis-1,4-polyisoprene with a salt of n-nitrosodiphenylamine. The possibility of substantial intensification of these processes is analyzed.
