Self-adhesive composition of hydrogenated block copolymers and protective film for smooth and rough surfaces

摘要

The invention relates to a self-adhesive composition of hydrogenated block copolymers or a mixture of such, comprising polymer blocks, formed of vinylaromatics (a - blocks), and those formed by polymerization of 1,3 - are used (b - blocks), wherein the self-adhesive composition with 25 to 100 parts by weight of polyisobutylene having a weight-average molecular weight m_W 200000 g / mol, 3 to 40 phr (per hundred rubber = based on the block copolymers) adhesive resin as well as 0,1 to 5 phr light stabilizers, based on 100 parts by weight of the block copolymers, is mixed.
