Abstract
The present invention relates to a composition which comprises at least one triblock copolymer, one terpene resin, one liquid component and one ethylene-vinyl acetate copolymer, and also to a process for preparing this composition, and to its use.
Claims6
A composition comprising:
- a) from 10% by weight of 50% by weight of a triblock copolymer of the formula (I)
- ABA, (I)
- where
- A is a block containing repeating units derived from styrene or substituted styrene and
- B is a block containing repeating units derived from one or more different dienes and the fraction of repeating units derived from styrene or a styrene derivative in the two A blocks is in total from 10 to 40% by weight,
- b) from 10% by weight to 60% by weight of an alicyclic terpene resin,
- c) from 10% by weight to 40% by weight of a component which is liquid at 20° C., which is selected from the group consisting of selected from the group consisting of a diene polymer, a poly-α-olefin, a refined mineral oil fraction comprising saturated aliphatic hydrocarbons and mixtures thereof, and
- d) from 10% by weight to 40% by weight of an ethylene-vinyl acetate copolymer whose vinyl acetate content is more than 40% by weight.
