Title:
修飾ポリテトラフルオロエチレン微粉末
Document Type and Number:
Japanese Patent JP3764752
Kind Code:
B2
Abstract:
Polytetrafluoroethylene (PTFE) fine powder is provided which exhibits both low rheometer extrusion pressure and high adhesion to wire by incorporating into the free powder the combination of perfluoro(alkyl) ethylene such as perfluoro(n-butyl) ethylene with fluoro(alkyl vinyl ether), such as perfluoro(propyl vinyl ether), or fluoroolefin such as hexafluoropropylene as modifiers of the PTFE fine powder. The modified PTFE fine powder is made by aqueous dispersion copolymerization of TFE with the modifying monomers, with the addition of molecular weight reducing agent towards the end of the polymerization reaction.
