  • Publication number: 20200283581
    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.
