Abstract

Arizidinosilicones of the general formula (1), wherein R1 represents H, C1-C12 alkyl, C2-C12 alkenyl, C2-C12 alkinyl, C7-C15 alkaryl, C7-C15 aralkyl, C3-C12 cycloalkyl and these groups can be substituted with Cl 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 of the selection of R1 and/or R4, and R3 represents SiRl3 or SiR12R4, and wherein R4 represents formula (2), and 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 includes 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(O)C(O), C(O)(CH2)m(C(O), C(S)NR1, CH2, 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 includes 0 to 18 carbon atoms, a is 0 or 1, f is an integer from 2 to 1000, n, m 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 smal…
