| abstract |
A multi-layer structure comprising at least two thermoplastic layers in which at least one layer comprises one or more antistatic compounds is described. The antistatic compounds are selected from perfluoroalkyl sulfonic acid salts, e.g. perfluoroalkyl sulfonic ammonium acid salts, perfluoroalkyl sulfonic phosphonium acid salts and perfluoroalkyl sulfonic sulfonium acid salts. The multi-layer structure may be selected from films, solid sheets and multi-walled sheets. |
