CROSSLINKED POLYTETRAFLUOROETHYLENE RESIN AND ITS PRODUCTION

Title:

CROSSLINKED POLYTETRAFLUOROETHYLENE RESIN AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JP2000086774

Kind Code:

A

Abstract:

To provide a method for producing a crosslinked PTFE resin having a network structure formed of lamination of branches derived from grafting without needing a material before treatment to extremely change its shape.

This method comprises irradiating a polytetrafluoroethylene resin with ionizing radiation at a temperature lower than its crystalline melting point and subjecting the resultant radicals to graft reaction with tetrafluoroethylene monomers, thus forming the crosslinked structure round the amorphous region and interface of the resin.
