Definitions

  • the present disclosure provides cis-polycycloolefins and methods for forming cis- polycycloolefins.
  • Polyolefins are widely used commercially because of their robust physical properties. For example, polyolefins having carbon-carbon double bonds along the polymer backbone are of commercial interest as rubber replacements/additives. Polyolefins are typically prepared with a catalyst that polymerizes olefin monomers. Polyolefins, such as polynorbornene, can be synthesized by olefin metathesis from olefin monomers, such as norbornene monomers. Olefin metathesis is an interchange of radicals between two compounds during a chemical reaction. For example, norbornene can be converted to polynorbornene by ring-opening metathesis polymerization (ROMP) using ruthenium catalysts. The resultant polynorbornene can be used in the rubber industry and has a glass transition temperature of 39.9°C.
  • catalysts and methods for forming polycyclopentene and polycyclooctene are highly trans (E) selective (greater than 80% trans (E) content of a formed polyolefin).
  • cyclopentene monomer has a very low ring strain of - 6.8 kcal/mol, which makes it a difficult monomer to polymerize using ROMP as compared to, for example, norbornene which has a ring strain of 27.2 kcal/mol.
  • Polyolefins having a high content (e.g., greater than 50%) of cis (Z) carbon-carbon double bonds along the polymer backbone are of commercial interest because of their low melting points (e.g., -20°C), low glass transition temperature (e.g. , -100°C) and slow rates of crystallization, which make them ideal candidates for rubber replacements or additives to provide low temperature operability.
