Chemical Recycling TRIZ Cases
- Isobutane Recycle Condensing for Stable Fluidized Bed Polymerization
Using isobutane in the recycle stream enables condensed-mode cooling in fluidized bed polymerization without the stickiness and fouling caused by heavier ICAs.
- Bis-Biphenylphenoxy Catalysts for High-Mw Alpha-Olefin Polymers
A bis-biphenylphenoxy catalyst enables C6-C14 alpha-olefin polymerization with very high molecular weight and narrow molecular weight distribution.
- Biphenylphenoxy Catalyst Composition for Multimodal Polyethylene
A biphenylphenoxy metal-ligand catalyst boosts ethylene polymerization selectivity and high-temperature molecular weight control.
- Multi-Catalyst Olefin Polymerization for Multimodal Molecular Weight Control
Combining bis-phenylphenoxy and phosphinimine catalysts enables hydrogen-tuned multimodal polyethylene with precise molecular weight distribution.
- Reversible Polymer Crosslinkers for Acid-Triggered Substrate Recycling
Acid-labile crosslinking bonds let coated substrates release polymer layers under acidic conditions, enabling recycling without formaldehyde.
- Multi-Catalyst Olefin Polymerization for Multimodal Molecular Weight Control
Combining CGC and phosphinimine catalysts with hydrogen tuning enables multimodal polyethylene with tailored molecular weight and process flexibility.
- Bis-Phenyl-Phenoxy Catalysts for Olefin Chain-Shuttling Control
Group III and lanthanide metal-ligand catalysts with chain transfer agents narrow molecular weight distribution while preserving olefin polymerization efficiency.
- Biarylphenoxy Group IV Catalysts for Narrow-Dispersity Olefin Copolymers
A biarylphenoxy Group IV catalyst enables chain transfer while maintaining high molecular weight, narrow polydispersity, and comonomer incorporation.
- Alpha-Olefin Feed Stream Pressurization for Comonomer Absorption
Staged pressurization improves alpha-olefin and comonomer absorption, cutting volatile reactant loss and feed complexity in solution polymerization.
