Abstract
Official abstract text for this publication.
A transparent antistatic composition based on polymethyl methacrylate (PMMA), including: 55% to 99.9% by weight of PMMA, and 0.1% to 45% by weight of at least one polyamide (PA) block-containing and polyether (PE) block-containing copolymer (PEBA) inlcuding polyethylene glycol (PEG), with respect to the total composition weight, said copolymer being characterized in that it includes in the range 50% to 80% by weight of PEG with respect to the total weight of copolymer.
