• 1. Dendrimer can greatly improve properties of reactive
dyes.
• Reactive dyes was used to treat jute fiber, the results
show that dendrimer modified jute fiber tinting strength
was increased by 30%, fixing strength increased 21%,
and light resistance 90%. Weihai CY Dendrimer
Technology Co., Ltd.-Professional Manufacturer for low
cost dendritic polymers. -The newest 4th class polymers.

• 2. Dendrimer-OH / titania composites used as metal
chelates.
• Dendrimer-OH / titania composites can be used as metal
chelates to treat wastewater with metal ions, especially
for industrial plating wastewater treatment. Optimum pH
value of electroplating wastewater that contain various
metal ions was different, Cu2 + and Cr3 + optimum
treatment pH value was 7, the metal ion removal rates
was 96.6%, 99.9%, and optimum treatment pH value of
Ni2+ was 9, removal rate was 99.8%. Weihai CY

• 3. Excellent adsorption properties of novel cyclodextrin
polymer of Zn2+.
• Cyclodextrin (CD) is cyclic oligosaccharides connected by
a different number of glucose molecules, and a class of
good clathrate material. β-CD and dendritic molecules
were used to synthesize novel polymer which is insoluble
in common solvents, through elemental analysis, Molar
ratio of CD and dendrimers was 2:1. The new polymer
was used to adsorb Zn2+ in simulate water at pH 5 to 6.5,
the initial concentration was 2.45mmol/L, Zn2+ adsorption
capacity reached 0.78mmol/g. Weihai CY Dendrimer

• 4. Great

property of dendrimers-nickel complex of cyclohexene oxide
catalysis.

• Dendrimers-nickel complex can well catalyze cyclohexene oxide
under solvent-free conditions, the main products were 2 –
cyclohexenol, 2 – cyclohexenone, 7 - Miscellaneous oxybis ring
[4,1,0] heptane-2 rings - one, and the total selectivity of the three
products in the total proportion of the reaction product was above
99%, 2 - cyclohexene selectivity can reach 44 % or more; molecular
oxygen which was environmentally friendly was used as oxidant,
solvent and reducing agent is not necessary. The catalyst preparation
method is simple and it’s insoluble in water and common organic
solvents, keeps active in water and air, reusable, meets the
requirements of green chemistry development. Weihai CY Dendrimer
Technology Co., Ltd.-Professional Manufacturer for low cost dendritic
polymers. -The newest 4th class polymers.

• 5. Improved rheological and mechanical properties of
dendrimer modified polyester.
• The ductility of the polyester was enhanced being
extruded together with dendrimer, but no increase in
tensile stress; after-condensation of the polyester can
improve tensile strength, but no change in ductility; aftercondensation of polyester with low proportion of dendritic
polymer can significantly improve the tensile stress and
ductility of material. Weihai CY Dendrimer Technology
Co., Ltd.-Professional Manufacturer for low cost dendritic
polymers. -The newest 4th class polymers.
