Title:
変性されたペルフルオロプラスチック及びその製造法
Document Type and Number:
Japanese Patent JP2007510029
Kind Code:
A
Abstract:
Modified perfluoroplastics and method for the production thereof. The invention relates to the field of chemistry and relates to modified perfluoroplastics that can be used, for example, in tribomaterials, and a method for the production thereof. Modified perfluoroplastics which, when processed in structural parts, lead to comparable gliding properties and improved wear resistances, and furthermore there is provided a simple and efficient method for production thereof. Modified perfluoropolymers are provided, the surface of which simultaneously exhibit -COOH and/or COF groups and reactive perfluoroalkyl-(peroxy-) radical centers, whereby further low-molecular and/or oligomeric and/or polymeric substances and/or olefinically unsaturated monomers and/or oligomers and/or polymers are coupled via the groups and/or to the centers. There is also provided a method for producing modified perfluoroplastics in which modified perfluoropolymers, which simultaneously exhibit -COOH and/or -COF groups and reactive perfluoroalkyl-(peroxy-) radical centers, are reacted with other substances through substitution reactions and/or addition reactions and/or radical reactions.
