| 摘要 |
The present invention relates to adhesives and sealants prepared from novel anionic block copolymers of mono alkenyl arenes, diphenylethylenes and conjugated dienes. The block copolymers are unhydrogenated or selectively hydrogenated and have mono alkenyl arene/diphenylethylene end blocks and conjugated diene mid blocks. The block copolymer may be combined with tackifying resins, oils and other components to form the adhesives and sealants of the present invention.
