摘要

This relates to a composition comprising a block copolymer structure has five Hydrogen Ababa(a) where the block is a block of Hydrogenated Vinyl Aromatic Polymer that has a level of hydrogenation of L over 90% and block (b Block) is a polymer of hydrogen dienoconjugadoAdo has a level of hydrogenation over 95%, characterized by: (a) a total of Number Average Molecular Weight of 70000 desde40000 (MNT),(a) where each block of Hydrogenated Vinyl Aromatic Polymer has a MNA from 8700 to 21000 and each Block (b) is a Hydrogenated conjugated Diene depolu00edmero of MNB from 2000 up to 12500, being the total amount of B from 10 to 35% by weight of the Copolymer is combined based on the weights of all the blocks a and B; useful for Injection Molding applications.
