AMPHIPHILIC BLOCK COPOLYMER

The invention relates to block copolymer comprising i) A first block wherein at least 65 mol-% of the repeating units of the first block are repeating units of the formula (I)-[CH2-CH2-O]-, ii) A second block wherein at least 90 mol-% of the repeating units of the second block are repeating units of...

Beschreibung
Zusammenfassung:	The invention relates to block copolymer comprising i) A first block wherein at least 65 mol-% of the repeating units of the first block are repeating units of the formula (I)-[CH2-CH2-O]-, ii) A second block wherein at least 90 mol-% of the repeating units of the second block are repeating units of at least one of formulae (II) or (III), wherein the groups R1, R2, and R3 independent of each occurrence are selected from hydrocarbyl groups having 1 to 40 carbon atoms, which are optionally substituted by ether or hydroxyl groups, and wherein the groups R1 and R2 are optionally linked to each other such that a nitrogen heterocyclic structure is present, iii) A third block which is different from the first block and the second block and which is more hydrophobic than the first block.
