APPLICATIONS
Neodymium Versatate is at the heart of Neodymium catalyzed butadiene polymerization.
Neodymium Versatate is easy-to-handle, high performance catalyst-precursor, enable the production of Butadiene rubbers with a "cis" content of 98% and a narrow molecular weight distribution, which are thus very ideally suited to 'green' tire applications.
Neodymium Versatate is used as Ziegler-Natta Catalyst.
Neodymium versatate was used as catalyst to perform solution 1,3-butadiene polymerizations.
Catalysts were synthesized and aged at 5 °C for 0–60 days.
Reactions were performed in the temperature range from 60 to 80 °C for 40–120 min.
The obtained polymer products were characterized by Fourier-transform infrared spectroscopy (FTIR) and gel permeation chromatography (GPC).
Neodymium Versatate dissolved in polymerization grade hexane is used in industrial catalytic processes.
Neodymium Versatate is applied as a catalyst for rare earth rubber, Neodymium Versatate can be used as a catalyst for rare earth butadiene rubber, rare earth isoprene rubber, and rare earth J isoprene rubber.
TECHNICAL ADVANTAGES
Neodymium Versatate catalyst exhibits a very high activity in polymerising butadiene. Typically over 95 % conversion efficiencies are achieved in 30 minute polymerisation tests.
The Butadiene Rubber has CIS contents in excess of 98 %, and the rubber molecules exhibit a high degree of linearity, leading to favourable physical properties.
The Butadiene Rubber molecular weight distribution is narrow, which has positive advantages in physical properties of the rubber, as well as allowing the long-term continuous runnability of the rubber manufacturing process.
The liquid Neodymium Versatate catalyst is stable at high solids contents over long time periods, and will maintain its catalytic efficiency in liquid storage for 2 years or longer.
Precipitation of an inactive Neodymium Versatate Sludge from the liquid catalyst will not occur.
In Neodymium Versatate catalyst, no excess additives of any kind are used to manipulate product stability, and hence no concern exists as to how these additives may interfere with the formation of the active catalyst complex.
The high activity of Neodymium Versatate Catalyst allows for the optimisation of the Neodymium to Aluminium ratios to levels not commonly reported in literature, thereby reducing overall catalysts system costs.
DESCRIPTION
Neodymium Versatate is used to manufacture a Ziegler-Natta catalyst, required for the polymerisation of butadiene.
The Neodymium Versatate Catalyst is reacted with a chlorine donor, such as a Di-alkyl Aluminium Chloride, or Ethyl Aluminium Sesquichloride (EASC), as well as an aluminium activator, such as a Di-alkyl Aluminium Hydride.
The product manufactured with Neodymium Versatate catalyst is a high CIS content, high impact resistant Butadiene Rubber suitable for tyre manufacture and other applications.
Neodymium Versatate Catalyst with a unique chemical procedure, unlike the chemical processes which are used to manufacture other Neodymium Catalysts that are available commercially elsewhere.
