Beschreibung
Zusammenfassung:	Vinylaromatic copolymers modified with at least one monomer deriving from (meth)acrylic acid having a block structure which comprises at least two blocks, M and N, in each of the blocks M and N, the concentration of the monomer deriving from (meth)acrylic acid ranges from 0.5 to 85% by weight, on the condition that between two adjacent blocks there is a difference of said concentration of at least 8 points and that the total concentration of said monomer deriving from (meth)acrylic acid in the block copolymer ranges from 20 to 60% by weight.
