Abstract
N-alkyl aziridine block copolymers of the general structure (1), wherein R1 represents H, C-Calkyl, C-Calkenyl, C-Calkinyl, C-Caralkyl C-Caralkyl, or C-Ccycloalkyl and these groups can be substituted with C1 or F partially, completely or in a mixed manner and/or may contain 0 to 5 heteroatoms selected from O, N, S; R2 represents a group selected from R1 and/or R4; R3 represents SiR1or SiR1R4, wherein R4 represents a group of the general formula (2), wherein A represents an (n+1) radical saturated, unsaturated or aromatic, linear, branched or cyclic hydrocarbon group that may contain 0 to 5 heteroatoms selected from O, N, S and that comprises 1 to 18 carbon atoms; B is selected from O, S, NR1; D is selected from C(O)O, C(O)NR1, C(O), C(S)NR1, CH; E represents a diradical saturated or unsaturated, linear, branched or cyclic hydrocarbon group that may contain 0 to 5 heteroatoms selected from O, N, S, and that comprises 0 to 18 carbon atoms; Q represents and α, ω-radical polyether chain of the general formula (3): —[O—CH]—, wherein g is 2 to 20; h is 1 to 1000; a is 0 or 1; f is an integer from 2 to 1000; n is an integer from 1 to 10; and x, y, z each represents 0 or an integer, the sum of which should range between 1 and 10000, with the proviso that if x is larger 0, y or z is smaller or equal x. There are many uses of these copolymers.
