| 摘要 |
The invention relates to the self-adhesive material of hydrogenated block copolymers or a mixture thereof, comprising polymer blocks of vinyl aromatics (A-blocks) and such made by polymerization of 1,3 dienes (B-blocks), mixing the self-adhesive material with 10 to 80 parts per weight, preferably with 10 to 40 parts per weight polyisobutylene with an average molecular weight Mw in relation to 100 parts by weight Mw of the blockcopolymeres. |
