NEW PROCESS FOR HIGH PERFORMANCE POLYMERS

NEW PROCESS FOR HIGH PERFORMANCE POLYMERS

CHALLENGE

The polymerization of Michael type based monomers is well-known and common technology. However, this common technology has its drawbacks and limitations. Radical initiated polymerizations are difficult to control with regard to tacticity and dispersity of polymers. Moreover, demanding mono- mers like acryl esters having bulky substituent groups are difficult to polymerize and can be obtained only in lowyieldsor with time and cost consuming processes. Tacticity and dispersity index are hardly or not to control for monomers like acrylo nitrile. With the known methods such polymerization reac- tions could be controlled only by using catalysts comprising noble metals or rare earth metals which cause high cost and are detrimental for the environment.

INNOVATION

The technology comprise a new implementation process for (meth) acrylates and analogous Michael monomers to form plastics which are used as so-called high performance polymers in important fields of application, such as cosmetics, automotive or pharmaceuticals.

A highly active catalyst system is used, by means of which the disadvantages of the conventional free-radical or anionic preparation methods can be overcome.

COMMERCIAL OPPORTUNITIES

The catalyst system is based on commercially available main-group element compounds, thus not requiring the use of toxic and/or expensive subgroup element catalysts. It fulfills important industrial requirements such as maximum efficiency, highest precision, and simple and controlled reaction guidance.

The catalyst system impresses with its enormous range of application (Figure 1). The inventive syntheses is

  • Simpler
  • More  cost-effective
  • Allows the conversionofmonomerswhichuntilnowhavenotyetbeenpolymerized
