|Basic activity directions||Were developed methods for the synthesis of polyfunctional complexsonates containing different heteroatoms and obtain various metalcomplexes based on them. On the basis of these compounds were derived chemical additives as stabilizers against of polymers, additives for motor oils and fuels, corrosion inhibitors as well as iniferters processes and catalysts for the polymerization, oligomerization and copolymerization of diene hydrocarbons and polyacrylates|
|Main scientific achievements||
On base of nikelditiophosfates designed multifunctional stabilizer "Stanaz." With its use in industry was released polyethylene composition and film having antistatic, resistance to heat and light exposure- UV rays with a large coefficient of and used in agriculture with a large economic effect.
Nickel-containing catalyst dithiosistems:
Organic dithioderivative of nickel (dithiophosphates-DTF-Ni, dithiocarbamates DTC-Ni or nickel xanthates - Kc-Ni) + alkylaluminumhalides (monocholrides or sesquichloride) for the process of obtaining a low molecular weight 1,4-cis polybutadiene, finding used as a film-forming in the paint industry;
The catalyst system Kobaltdithiofosfat catalytik systems: organic O, O-dithiofosfates cobalt (CTF-Co or DIPDTF-Co) + alkylaluminumhalides (monochlorides or sesquichloride). Process for producing high molekular weids1,4-cis polybutadiene (containing 1.4 - cis-units over 92-95%), which find application in the tire and rubber industry, as well as in the synthesis of high-impact polystyrene;
Kobaltditiokarbamat catalyst system: N, N-dithiocarba-mates cobalt (Co-DTC) + alkilaluminiymhalide (monochloride or sesquichloride) to obtain the high molecular weids cis- 1,4 polybutadiene content of 35% 1,2-units, used in the tire industry as substitute styrene butadiene rubber, as well as in the synthesis of high impact polystyrene;
Kobaltxsantogenat catalyst system: xanthogenates cobalt (Co-Xs) + trialkyl aluminum (TIBA or TEA) process for producing syndiotactic 1,2-polybutadiene with different crystallinity, which find application in the footwear industry, as well as during manufacture of biodegradable films, packaging and container.
These catalytic ditiosistems, unlike their known analogs, along with high catalytic activity in the polymerization of butadiene, are also highly stabilizing efficiency storage polybutadiene, as well as act as a vulcanization accelerator in the manufacture of rubber. Therefore, the polymerization of butadiene using nickel- and cobalt-containing catalyst dithiosistem not require washing of the polymer catalyst residues and additional stabilization with expensive antioxidants. All this opens up opportunities for the creation of environmentally friendly production of synthetic rubbers, in particular polybutadienes.
All studies on the polymerization of butadiene using the these catalyst dithiosistems conducted under conditions close to factory conditions, repeatedly tested the activity of these systems and implemented in the production of synthetic rubber.
When implementing this process excludes energy- intensive and difficult to implement mye- washing step and the polymer stabilization of the polymer obtained with the use of expensive anti- oxsidants, which leads to the creation of environmentally friendly production technology polybutadiene varnish and achieve high economic effet.Additional economic benefit is achieved by using butadiene comprising pyrolysis fraction C4instead of pure butadiene.
Kobaltdithiofosfat catalytic systems provides a high-molecular 1,4- cis polybutadiene content of 1,4-cis –units 96-98% and took pilot and industrial tests of JSC “EZSK” Russia and in firm “PETKİM”, Turkey.
In the application of these catalytic systems is also eliminated in the deterging catalyst residues from the polymer and further stabilization.
Kobaltksantogenat catalytic systems provides a high molecular weight syndiotactic 1,2- polibutadiene different crystallinity. Sindiotakcal 1,2- polybutadiene having a high crystallinity (70%) is an analogue of the polymer produced by UBE POL(Japan) and is used in the preparation of polybutadienes and hardened during manufacture of various bottles, films, tar (similar to those which are made of polypropylene).Developed a one-step method for producing reinforced polybutadiene by polymerizing butadiene in the presence kobaltdithiofosfat ( cobalt- dithiocarbamate) and kobaltksantogenat catalyst systems.Syndiotactic 1,2- polybutadiene is a low crystallinity(15-25%) is an analogue of polybutadiene sold by JSR (Japan), and finds use in the shoe industry and in the manufacture of films, bottles and other containers.
Kobaltdithiokarbamat catalytic systems allows to obtain high molecular 1,4- cis polybutadiene with a content of up to 35% of 1,2- units, that is analog polibutadiene firm JSR (Japan) and is used in the tire industry to replace the styrene – butadiene rubber, as well as the manufacture of high impact polystyrene. This rubber has all the positive properties of styrene-butadiene and butadiene of general purpose rubbers and rubber tread on the basis of his best qualities differ in wear resistance for, grip, slip resistance on wet pavement and frost.
