Abstract
The invention provides a PTFE-containing aqueous dispersion composition which is excellent in mechanical stability and scarcely allows the formation of agglomerates due to fibrillation of the PTFE resin during transportation or processing thereof. This invention is a polytetrafluoroethylene-containing aqueous dispersion composition comprising a polytetrafluoroethylene resin (A), a hydrocarbon-derived nonionic compound (B) and a water-soluble high-molecular compound (C) having no oxygen atom in the main chain thereof.
