1. A composition comprising:
- (a) a modified randomly branched polyethyleneimine or polyoxazoline polymer without a core having a molecular weight of from about 500 to about 1,000,000 and comprising a functional group for branch formation, wherein said functional group is selected from the group consisting of —
NH2, —
NHR, —
COOR, —
COOH and a combination thereof, wherein R is an aliphatic or aromatic group; and
wherein said functional group for branch formation is produced by reaction with a methyl acrylate, an ethylenediamine or both;
(b) a bioactive material, wherein said bioactive material comprises a biological polymer, a hormone, a neurotransmitter or a drug; and
(c) a carrier, excipient, diluent or combination thereof,wherein said composition is used to carry said bioactive material in or on a subject.

Abstract
A conjugate of a modified randomly branched asymmetric polymer without a core and a member of a binding pair is described. The modified randomly branched asymmetric polymer can contain chain branches, terminal branches or both. The modified randomly branched asymmetric polymer can contain random asymmetric branches or random asymmetric junctions. The binding pair can be an antibody, antigen or a ligand. The conjugate includes a drug.
