Copolymere of hydrophobe modified polyesteramide-succinimide and its use

Abstract

Abstract Copolymers of aspartic acid and N-substituted aspartamides are new. Polyamino acid copolymers comprising at least 75 mol. % of units of formula (I), (II) or (III), including at least 1 unit of formula (I;R<1>=R<4>), at least one unit of formula (II) and no more than 20 wt. % of units of formula (II), are new: A = a group of formula A1 or A2: R<1> = R<4>, R<5> or R<6>; R<2> = 1-30C alkyl, alkenyl or aryl; 1-22C hydroxyalkyl or aminoalkyl containing 1-6 OH and/or amino groups, optionally acylated with 1-22C carboxylic acids; or R<5>; R<3> = H or R<2>; R<4> = H, alkali(ne earth) metal or (NR<7>R<8>R<9>R<10>)<+>; R<7>-R<10> = H or 1-22C alkyl, alkenyl or hydroxyalkyl; R<5> = R<11> or YR<11>; R<11> = 6-30C alkyl or alkenyl; Y = a chain of 1-100 oxyalkylene units; R<6> = 1-5C alkyl or alkenyl; B = the residue of a proteinogenic or nonproteinogenic amino acid.
