Abstract:
A process for the preparation of a free flowing molding powder, consisting essentially of:mixing powdered solids comprising a non free-flowing, suspension-polymerized, non-melt-processable, finely-divided tetrafluoroethylene polymer, with an aqueous medium containing at least one volatilizable trialkylamine oxide, said trialkylamine oxide being present in an amount of 0.1 to 2% by weight, based on the weight of the solids,to obtain moist agglomerates of powdered solids containing said trialkylamine oxide, anddrying the moist, powdered solids to obtain free-flowing powder which comprises the resulting tetrafluoroethylene polymer agglomerates, said free-flowing powder having an average particle size greater than 20 .mu.m.
