In the formula (2), R.sup.5 is an alkoxy group selected from the group consisting of a methoxy, an ethoxy and a propoxy group. In the formula (3), w is 2 or 3. ##STR00001##

Provided herein are polymeric α-hydroxy aldehyde or α-hydroxy ketone reagents which can be conjugated to amine-containing compounds to form stable conjugates in a single-step reaction. In selected embodiments, the polymeric reagent itself incorporates an internal proton-abstracting (basic) functional group, to promote more efficient reaction. The substituent is appropriately situated, via a linker if necessary, to position the group for proton abstraction, preferably providing a 4- or 5-bond spacing between the abstracting atom and the hydrogen atom on the α-carbon. Also provided are methods of using the reagents and stable, solubilized conjugates of the reagents with biologically active compounds. In preferred embodiments, the polymeric component of the reagent or conjugate is a polyethylene glycol.

Catalyst complexes include a zinc hexacyanocobaltate with M.sup.5 metal and M.sup.6 metal or semi-metal phases, wherein M.sup.5 metal is gallium, hafnium, manganese, titanium and/or indium and the M.sup.6 metal or semi-metal is one or more of aluminum, magnesium, manganese, scandium, molybdenum, cobalt, tungsten, iron, vanadium, tin, titanium, silicon and zinc and is different from the M.sup.5 metal. The catalysts are highly efficient propylene oxide polymerization catalysts characterized by rapid activation, short times to the onset of rapid polymerization and high polymerization rates once rapid polymerization has begun.

The present invention relates to an anhydrosugar alcohol-alkylene glycol composition, an anhydrosugar alcohol-based urethane-modified polyol composition, and use thereof for epoxy resin composition.

Methods are provided for producing bio-oil polyols, alkoxylating bio-oil polyols to provide polyols, and for employing the alkoxylated bio-oil polyols for making polymers or copolymers of polyesters or polyurethanes.
