Maleic rosin has been added to the surface of wood flour in the form of monoester, i.e., the formation of esterified wood flour bearing a pendent carboxylic group. The rheological study showed that the complex viscosity η(superscript *, storage modulus and loss modulus of WF-HDPE composites decreased firstly and increased afterward and declined lastly as the dosage of maleic rosin increased, however, the viscosity of the composite melts decreased as a whole. After the modification of wood flour, the rheological properties of composite melts were improved markedly. According to the mechanical test it was indicated that, by proper treatment of wood flour with maleic rosin, the tensile strength and flexural strength of WF-HDPE increased obviously.

Nm~3,μ= 4.836 mm~(-1), F(000)= 677, R = 0.0403, wR = 0.0673. Both of the complex adopt distorted trigonal bipyramidal geometry, with the basal plane defined by the SS atoms of the tridentate ligand and the oxo-group. The N of the tridentate ligand and the S of the monodentate ligand occupy two apical positions. Ionization of the sulphur atoms leads to a neutral compound.

In all those complexes, no matter which conformation IDA assumes (mer- or fac-style), the two 0 atoms of 1N2O are both from carboxylic hydroxyl.
