Functional polyolefins containing a terminal functional group; the block copolymers that can be obtained from such polyolefins by reaction with polymers reactive with the functional groups and the precursors used for the preparation of the functionalized polyolefins, which are made of olefin polymers terminated at one end with ZnR groups where R is an alkyl or aryl radical with 1-10 carbon atoms.

Monofunctional polymers of olefins and block copolymers obtained

Bimodal star-block copolymers are disclosed containing from 60 to 90% by weight of an aromatic vinyl monomer and from 40 to 10% by weight of a conjugated diene, said copolymers having the general formula:

Bimodal star-block copolymers, showing excellent optical properties and
