ABSTRACT:
A water soluble polymer is described, the water soluble polymer comprising multiple hydrolytically degradable carbonate linkages in a backbone and, for each carbonate linkage in the backbone, an oligomer linked thereto by the carbonate linkage, wherein the oligomer is branched and, prior to being linked by the carbonate linkage, has the formula:in-line-formulae description="In-line Formulae" end="lead"?R3[O—(—CHR1CH2—O—)n—]mHin-line-formulae description="In-line Formulae" end="tail"?where R3is a core branching moiety, R1is H, (n) can range from 2 to 2000, and m is at least 3.
