Abstract
The invention relates to mixtures composed of ethylene-vinyl alcohol copolymers and of crosslinkable rubbers having reactive groups and their use for production of moulded items with good barrier properties. The inventive mixtures in particular feature the good barrier properties and high impact resistance particularly at low temperatures, with a resultant broad application profile for these mixtures.
Claims7
Mixtures composed of
- a) ethylene-vinyl alcohol copolymers whose content of ethylene groups is from 15 to 60 mol %, whose content of vinyl alcohol groups is from 40 to 85 mol % and whose content, if appropriate, of vinyl ester groups is at most 20 mol % and
- b) crosslinkable rubbers whose TG value is ≦−20° C., where the rubbers have been modified with reactive groups and the content of modifying groups is from 0.01 to 5 mol %,
- where the amount of component a) makes up from 30 to 95% by weight, based on the amount of the entire mixture.
