<B> "BARRIER LAYER COMPOSITION FOR PLASTIC BODIES" <D>. The present invention describes a barrier layer composition that is applied to at least one surface of a plastic body, preferably a hollow polyolefin body, having the following composition: (a) 35 to 75% by weight of a metal oxide sol containing epoxide or halogen and a metal oxide sol containing epoxide; (b) 20 to 60% by weight of a maleic hemiac acid ester copolymer containing fluorine or sulfur or a maleic hemiac acid amide copolymer fluorine or sulfur, having the general structural formula below: where M is a vinyl monomer; X is oxygen, nitrogen; Y is - (CH ~ 2 ~) n-SO ~ 3 ~ H, - (CH ~ 2 ~) n-F, - (CF ~ 2 ~) n-H; and n ranging between 2 and 12; (c) 0.5 to 5% by weight of a catalyst based on one or more tertiary amines. |
