<p>Amphiphilic copolymer comprising at least two keto-amine structural units (I) and (II), excluding keto-amine diblock copolymers (III), where (I) is hydrophilic, and (II) exhibits more hydrophobicity than (I), is new. Amphiphilic copolymer comprising at least two keto-amine structural units of formula (-[C(=O)-CH(R 2>)-N(R 1>)] n-) (I) and (-[C(=O)-CH 2-N(R 3>)] m-) (II), excluding keto-amine diblock copolymers of formula (X-([C(=O)-CH(R 2>)-N(R 1>1>)] n1-[C(=O)-CH 2-N(R 1>3>)] m1) blk-Y 1>) (III), where (I) is hydrophilic, and (II) exhibits more hydrophobicity than (I), is new. R 1>CH 3or ethyl; R 2>CH 3or H; R 3>2-21C alkyl (optionally branched or cyclic), or aryl; n, m : greater than 1; n1 : 30-70; m1 : 10-40; R 1>1>CH 3; R 1>3>n-butyl; X : n-butylamine; and Y 1>H.</p> |
