Aimed to achieve higher gene delivery efficiency,PG6-PEIs were designed with dendrimer structure and highly condensed positive surface charges,which were obtained through grafting polyethylenimines(PEIs)with different molecular weights to a polyglycerol core(PG6).

The improvement of method determining hydroxyl value in polyglycerol;

Nonionic surfactant polyglycerol rosin ester was synthesized by reaction of rosin with polyglycerol.

The rosin-based nonionic surfactant was synthesized by the reaction of rosin and polyglycerol.

Their properties are measured,and indicate alkylphenoxyploy(hydroxypropylene oxide) surfactant is better than poly(ethylene oxide)surfactant.

In this paper, we present a new method for determination of uric acid in the presence of high concentration of vitamin C by different pulse voltammetry using poly glycine modified carbon microelectrode.

As raw materials for the production of cosmetics,polyglycerol esters may use as emulsion,excipient,wetting agent,softener.

Several kinds of polyglycerol esters were synthesized by reaction of fatty acid with polyglycerol and their surface physicochemical properties were investigated.
