Metallocenes TRIZ Cases
- Metallocene Catalyst Composition for Wide-MWD Olefin Polymerization
Bulky-substituted metallocene with a carrier and cocatalyst boosts olefin polymerization activity while widening molecular weight distribution.
- Metallocene Catalyst Composition for Broad Olefin Polymer MWD
A tailored metallocene catalyst composition raises olefin polymerization activity while broadening molecular weight distribution and branching.
- C1-Symmetric Metallocene Catalysts for Comonomer-Tolerant Polypropylene
Asymmetric bridged metallocenes keep catalyst activity with higher alpha olefins and dienes, enabling in-reactor high-melt-strength polypropylene.
- Carbazole-Substituted Metallocene Catalyst for Soluble Olefin Polymerization
A carbazole-substituted transition metal catalyst improves hydrocarbon solubility and high-temperature activity for high molecular weight olefin polymers.
- Hybrid Supported Metallocene Catalyst for Biaxially Stretched Polyethylene
A hybrid supported metallocene catalyst enables single-reactor polyethylene copolymerization with better stretching stability, heat resistance, and film properties.
- Metallocene Catalyst Composition for High-Molecular-Weight COC
A tailored metallocene and cocatalyst system boosts ethylene-cyclic olefin copolymer activity, copolymerization, and molecular weight.
- Metallocene compound, catalyst composition, olefin polymerization method, and ethylene-cycloolefin copolymer and preparation method therefor
A heteroatom-bridged metallocene catalyst raises activity, improves ethylene-cycloolefin copolymerization, and delivers higher polymer molecular weight.
- Metallocene-Diorganomagnesium Catalyst for Higher Functional Polymer Content
An asymmetric diorganomagnesium co-catalyst boosts metallocene activity while raising functional group content in olefin and diene polymer synthesis.
- Ph-TRAP Crystalline Alcoholate for Stable Ligand Isolation
A crystalline n-BuOH solvate turns unstable Ph-TRAP into an air-stable, easily purified ligand form for practical asymmetric hydrogenation.
- Preparation of catalyst system
A single impregnation route combines boron and aluminoxane cocatalysts to raise metallocene catalyst activity for high molecular weight polypropylene.
