    摘要: Polymers of the monomer N-acryloylmorpholine having a single reactive moiety at one end of the polymer chain have the following structure: ##STR1## wherein -Z-X-Y is a polymer capping moiety, such as mercaptan, X represents a saturated residue of a linear or branched aliphatic series of the general structure --C.sub.r H.sub.2r -- in which r is an integer from 1 to about 12, Y is a reactive moiety and typically will be one of the reactive moieties commonly known in PEG chemistry, such as an --OH, --COOH, or --NH.sub.2 group, Z is a moiety that readily reacts to cap a polymer free radical, and n is an integer from about 6 to 280, which yields a number average molecular weight ("M.sub.n ") of from about 1,000 to 40,000. The monofunctional polymer is a suitable alternative to monofunctional PEG for modification of substances having biological and biotechnical applications.

    摘要: Multi-armed, monofunctional, and hydrolytically stable polymers are described having the structure ##STR1## wherein Z is a moiety that can be activated for attachment to biologically active molecules such as proteins and wherein P and Q represent linkage fragments that join polymer arms poly.sub.a and poly.sub.b, respectively, to central carbon atom, C, by hydrolytically stable linkages in the absence of aromatic rings and ester groups in the linkage fragments. R typically is hydrogen or methyl, but can be a linkage fragment that includes another polymer arm. A specific example is an mPEG disubstituted lysine having the structure ##STR2## where mPEG.sub.a and mPEG.sub.b have the structure CH.sub.3 O--(CH.sub.2 CH.sub.2 O).sub.n CH.sub.2 CH.sub.2 -- wherein n may be the same or different for mPEG.sub.a and mPEG.sub.b and can be from 1 to about 1,150 to provide molecular weights of from about 100 to 100,000. The mPEG disubstituted lysine can be purified from a reaction mixture by chromatography in water, including gel filtration chromatography and ion exchange chromatography because the carboxyl group is ionizable. Impurities are removed, including unreacted mPEG and mPEG monosubstituted lysine, to provide the polymer in pure form. Ion exchange chromatography permits fractionation of a greater amount of polymer per run.
