Abstract
New biologically active drug polymer derivatives, namely peptides or protein derivatives, are useful medicaments and are represented by the generic formula:
RO--(CH.sub.2 --CH.sub.2 O).sub.n --(CO)--NH--X--(CO)--NH--Z (I)
wherein
R represents a lower alkyl group,
n is an integer comprised between 25 and 250,
X when combined with adjacent NH and CO groups represents an amino acid or a dipeptide or tripeptide residue, and
Z when combined with the adjacent NH group represents a biologically active peptide or protein or NH or NH2 containing drug residue.
