ABSTRACT:
A branched and hydrogenated block copolymer can be defined by the formula [(EB).sub.1 --HT--A--(EB).sub.2 ].sub.n X, where (EB).sub.1 and (EB).sub.2 are hydrogenated polydiene blocks, A is a polyvinylaromatic block, HT is a random copolymer segment made up of hydrogenated dienic monomeric and vinylaromatic units, X is a coupling radical having a valence equal to n, and n is a whole number ranging from 3 to 20.
This kind of block copolymer shows excellent mechanical characteristics and resistance to atmospheric agents, even when used in combination with other resins.
