Functionalized polyglycine-poly(alkylenimine) copolymers, their preparation and use for preparing active ingredient formulations and special-effect substance formulations

Copolymers containing 10 to 95 mol % of structural units of the formula (I), 5 to 90 mol % of structural units of the formula (II) and 0 to 20 mol % of structural units of the formula (III)

• —NR1—CHR3—CHR4— (I),
• —NH—CO—CHR7— (II),
• —NH—CHR9—CHR10— (III),
• or
• copolymers containing 10 to 95 mol % of structural units of the formula (IV), 5 to 90 mol % of structural units of the formula (V) and 0 to 20 mol % of structural units of the formula (VI)
• —NR1—CHR3—CHR4—CHR5— (IV),
• —NH—CO—CHR7—CHR8— (V),
• —NH—CHR9—CHR10—CHR11— (VI),
• wherein
• R1 is a radical of the formula —CO—R2, of the formula —CO—NH—R2 or of the formula CH2—CH(OH)—R12,
• R3, R4, R5, R7, R8, R9, R10 and R11 independently of one another are hydrogen, methyl, ethyl, propyl or butyl,
• R2 is selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, aralkyl, —CmH2m—X or —(CnH2n—O)o—(CpH2p—O)q—R6,
• R6 is hydrogen or C1-C6 alkyl,
• R12 is selected from the group consisting of hydrogen, alkyl, alkenyl, cycloalkyl, aryl or aralkyl,
• X is selected from the group consisting of hydroxyl, alkoxy, carboxyl, carboxylic acid ester, sulfuric acid ester, sulfonic acid ester or carbamic acid ester,
• m is an integer from 1 to 18,
• n and p independently of one another are integers from 2 to 4, where n is not equal to p, and
• and q independently of one another are integers from 0 to 60, at least one of o or q not being equal to 0, the percentages being based on the total amount of the structural units of the formula (I), (II) and (III) or of the formula (IV), (V) and (VI).
