Abstract
The invention relates to a block copolymer and more especially to a thermoplastic elastomer block copolymer. The block copolymer is a diblock (block A)-(bloc B) copolymer, a triblock (block A)-(block B)-(block A), or a triblock (block A)-(block B)-(block C) copolymer, wherein block A is a stiff block, block B is a soft block, and block C is a stiff block. Block A or Block B comprises repetitive units deriving from segregation monomers.
