    Synthesis and Modification of Reactive and Functional Polymers


Fields of Work

Synthesis of α-olefin-based copolymers and nanocomposites

  • Controlled metallocene-catalyzed polymerization, e.g. copolymerization of propene with polar comonomers and synthesis of polar macromonomers
  • Monitoring of the reaction process using "real-time" ATR-FTIR spectroscopy
  • Structure-property relationships of the synthesized propene copolymers (using different analytical methods in cooperation with other colleagues).
  • Synthesis of PP nanocomposites by in situ polymerization

Aim and Motivation:

  • Improve the adhesion properties of polyolefin coatings and the interaction of the phase boundaries of polyolefins with other polymers in blends, polymer composites and multilayer films
  • Generate activated polypropylene surfaces or interfaces in blends containing polar modification of polyolefin particularly polypropylene
  • Search for potential applications as compatibilizer for inorganic nanoparticles or as emulsifiers.

Methods:

  • Synthesis of defined structure graft copolymer with adjustable parameters, such as length of the side chains and the main chain, stereoregularity of the main chain, side chain density and distribution, for example, the direct copolymerization of propene with functional comonomers or macromonomers.
  • Synthesis of olefin block copolymers by means of controlled polymerization of olefins and using post- metallocenes
  • Synthesis of polyolefin nanocomposites by in situ polymerization
  • Use of characterization methods of the Institute et al NMR, DSC, TEM, SEM, AFM, WAXS, XPS
  • Kinetic studies of the polyolefin copolymerization and in-situ polymerization in real time by recording FTIR spectra characteristic absorption bands of the reactants, this use of the in-line ATR-FTIR spectroscopy in conjunction with an ATR probe at the reactor bottom of a autoclave vessel in cooperation with colleagues of the Analysis Department
