Abstract
The invention relates to a process for drying a moist polymeric material to obtain a dried polymeric material, comprising the steps of: mixing the moist polymeric material with an aqueous solution of a carbohydrate to afford a mixture of the moist polymeric material with the carbohydrate; and heating and/or filtering the mixture of the moist polymeric material with the carbohydrate to remove an amount of volatiles to obtain a predried polymeric material having a volatiles content VC(pre-drying step); fluidizing the pre-dried material in a fluidized bed in order to further remove an amount of volatiles to obtain the dried polymeric material having a volatiles content VC(fluidized bed drying step); and withdrawing and collecting the dried polymeric material from the fluidized bed; wherein VCis higher than VCand the moist polymeric material comprises at least a polymeric material, said polymeric material comprises fluorine permanently bonded to said polymeric material. The invention further relates to a dried polymeric material obtainable by the process of the invention. Furthermore, the invention relates to various uses of the process of the invention as well as to various uses of the dried polymeric materials.
