formula CH2=CH-CH2-CH3, produced by the catalytic dimerization of ethylene.
It is widely used in the polymer industry as a co-monomer in polyethylene production,
enabling manufacturers to precisely control polymer density and optimize mechanical
performance across a wide range of applications.
Applications :
• Co-monomer in polyethylene production to control density and improve properties
• Feedstock for butadiene and polybutadiene (synthetic rubber) production
• Petrochemical intermediate for industrial manufacturing
