| abstract |
The present invention describes thermoplastic elastomer compositions prepared from: (A) a block copolymer, an aromatic vinyl compound and a conjugated diene and / or a selectively hydrogenated product of said diene, (B) of an aromatic vinyl polymer having a functional group which reacts with the functional group of component C, and (C) a rubber polymer having a carboxyl, an amino, an epoxy and / or a hydroxyl group. The present invention also describes a process for preparing these compositions by melt mixing the three components. |
