Abstract:
1. An N-alkylaziridine block copolymer of a formula (I): wherein R1 denotes a R1 radical selected from the group consisting of H, C R2 denotes a R2 radical selected from the group consisting of R1 and R4; R3 denotes SiR1 R4 is a representative of the general formula (II): wherein A=(N+1)-valent saturated, unsaturated or aromatic, linear, branched or cyclic hydrocarbon radical comprising 1 to 18 carbon atoms and which may contain 0 to 5 hetero atoms selected from the group consisting of O, N and S; B=a representative selected from the group consisting of O, S, and NR1; D=a representative selected from the group consisting of C(O)O, C(O)NR1, C(O), C(S)NR1 and CH E=a divalent saturated or unsaturated, linear, branched, or cyclic hydrocarbon radical which comprises 0 to 18 carbon atoms and which may contain 0 to 5 hetero atoms selected from the group consisting of O, N and S; Q=an α, ω-polyether chain of the general formula (III): x, y and z each represent either 0 or integers whose sum is between 1 and 10,000 and if x is greater than 0, y or z is less than or equal to x.
