Abstract

The invention relates to a plastic composition that contains 30 to 99 % by weight of a plasticized polyvinyl alcohol and 1 to 70 % by weight of a polyolefin maleic anhydride copolymer. The invention further relates to a method for producing said compositions and to the use thereof, especially as a barrier medium in fuel tanks.

Claims

AMENDED CLAIMS [received at the International Bureau on 16 April 2002 (16.04.02); original claims 1-17 replaced by amended claims 1-16 (3 pages)]
