Acetylene chemistry

Vinylether Monomer

We manufacture vinyl ether monomer using acetylene obtained from our ethylene plant as a raw material. The vinyl ether monomer is manufactured by allowing acetylene to react with alcohol under basic catalyst.
This method is generally called the Reppe reaction.

Various reactivities

Although cation polymerizability of vinyl ether monomers is well known generally, a part of the vinyl ether has radical polymerizability. Since we have our unique patent technology, ask us (Project Development Section).
Vinyl ether can perform not only homopolymerization but also copolymerization with glycidyl ether monomer and acrylate/ methacrylate monomer, and it performs complete alternating copolymerization with monomers with high electron accepting property (fluoroolefin and maleic anhydride).
In addition, vinyl ether monomer has reactivity with various reactive functional groups, such as the acetalization reaction and enethiol reaction.
