15 Claims

1. A transparent antistatic composition based on a polymethyl methacrylate (PMMA) polymer, comprising:

65% to 93% by weight of the PMMA polymer, wherein the PMMA polymer is modified with a PMMA organic additive selected from the group consisting of lubricants, UV stabilizers, thermal stabilizers or mixtures thereof; and

7% to 35% by weight of at least one polyamide (PA) block-containing and polyether (PE) block-containing copolymer (PEBA) comprising polyethylene glycol (PEG),

with respect to the total composition weight,

wherein said copolymer comprises about 60% by weight of PEG with respect to the total weight of copolymer; and

wherein the composition does not contain an organic salt,

in which said copolymer is selected from: PA6-PEG, PA11-PEG, PA12-PEG, PA10.10-PEG, PA10.12-PEG and mixtures thereof,

wherein the composition has a haze value less than 10%.
