Title
(EN) GRAFTED FLUOROPOLYMER POWDERS
(FR) POUDRES DE POLYMERES FLUORES GREFFES
Abstract
(EN)
Compounds containing polar functional entities can be grafted onto the surface of fluoropolymer powders to obtain grafted fluoropolymer powders having modified surface characteristics but without modifying the bulk of the polymer in the particle. The grafted fluoropolymer powder is effective in such uses as an adhesive to join dissimilar materials.
(FR)
On peut greffer des composés renfermant des unités polaires fonctionnelles sur la surface de poudres de polymères fluorés pour obtenir des poudres de polymères fluorés greffés, ayant des caractéristiques de surface modifiées, mais sans modifier la masse du polymère dans la particule. La poudre de polymère fluoré greffé est utile dans des applications telles que des adhésifs pour coller ensemble des matériaux différents.
