Abstract: The present invention relates to elastomeric thermoplastic polymers (ETP) and especially technical polymers with high added value used in varied sectors, such as electronics, motor vehicles or sport. The present invention more particularly relates to copolymers containing polyether blocks and polyamide blocks, abbreviated as “PEBA”, which have good antistatic properties. Even more particularly, the invention relates to a copolymer containing at least one polyamide (PA) block, at least one polyethylene glycol (PEG) block and at least one block that is more hydrophobic than the PEG block. A subject of the invention is also a process for synthesizing such thermoplastic elastomers which have good antistatic properties and the use thereof in any type of thermoplastic polymer matrix in order to afford this matrix antistatic properties.

Abstract: A method for impregnating strands or strips of natural fibres, using the following successive steps: i) the impregnation of the strands or strips by immersion in a bath containing a fine aqueous polymer dispersion; followed by ii) the drying of the strands or strips using a heating system, with the progressive elimination of the water and the gradual melting of the polymer, and the coating of the strands or strips and the molten polymer incorporated into the core of the strands or strips as a binder between the fibres; iii) optionally, the forming of the treated strands or strips into their final shape; and iv) the cooling of the treated strands or strips. The aqueous polymer dispersion comprises at least one semi-crystalline or amorphous polymer and, in the case of an amorphous polymer, has a Tg varying between 50° C. and 175° C.
