摘要： A fluoropolymer [polymer (F)], a polymerisation process for its manufacture, and a moulding process using such fluoropolymer [polymer (F)].The polymerisation process comprises polymerising at least one fluorinated monomer in a polymerization medium, in which the polymerization medium is mixed by means of a stirring system comprising at least two counter-rotating impellers. Surprisingly and advantageously, the polymerization occurs without fouling or deposit formation on the reactor walls, and moreover, occurs with improved homogeneity, without composition, pressure or temperature gradients, thus enabling obtaining homogeneous polymer composition with no risk of local overheating.A polymer (F) obtained from such process has improved morphology (percentage of organized structures, i.e. of particles of regular shape) and, hence, has good free flowing properties which make it suitable for being processed by compression moulding with no need of intermediate milling or grinding process or other size reduction process.
