摘要

Composition of dendrimers comprising a mixture of dendrimers of different molecular weights of formula (Corex) (DrM) x, or a tautomeric form thereof, or a salt thereof, or a solvate thereof, in which x is an integer from 3 to 6, and in which: A) The nucleus represents any of the combinations of: A.1) ** (See formula) ** when x = 3; A.2) ** (See formula) ** when x = 4; A.3) ** (See formula) ** when x = 5; A.4) ** (See formula) ** when x = 6; and B) D represents ** (See formula) ** C) M represents R1p or R2p, in which: C.1) R1 is: ** (See formula) ** and C.2) R2 is ** ( See formula) ** and D) R3 is D or M; E) r is p-1; F) p is 2n-1; G) n is an integer from 1 to 10; and H) X is selected from the group consisting of (CQ2) aCQ3 and CH2-O-CH2-Ph, in which Q independently represents H or halogen, Ph represents phenyl, is already an integer from 0 to 16.
