PAMAM dendrimer modified silica particles has great application value in water purification.
Silica particles modified by pamam can effectively adsorb anionic dyes and surfactant in the water, in particular C18G1S showed the highest binding affinity to the anionic surfactant. The adsorption isothermal studies indicated that adsorption of surfactants on C18GnS was due to the assistance of hydrophobic interaction between the aliphatic peripherals on the dendron and the
alkyl tail on the surfactant. The anionic targets adsorbed on the surface modified silica particles can be released at alkaline condition because of the deprotonation of PAMAM dendron, which suggests the convenient recovery and reuse process. Counting in the cost efficiency and environmental low load, as-prepared amphiphilic dendron-modified silica is a promising solid phase adsorbent for water purification.

Hyperbranched polymers can greatly improve shear strength and adhesion of epoxy and polyurethane adhesives. Highly branched polymer PAMAMs (HPBs) becomes a new kind thermosetting adhesive and related adhesion promoter, interfacial adhesion and durability have been significantly increased (100-250%) after modifying, while at lower concentrations it can effect best, it has wide applications and can be used as a binder for variety of plastic and metal.

Effect of novel hyperbranched polyester on PVC mechanical and rheological properties.Hyperbranched polyester can effectively improve the processing fluidity of PVC:
(1) Tensile properties of hyperbranched polyester modified PVC is sensitive to the processing temperature , at 170 ℃ open mill temperatures, hyperbranched polyester/PVC tensile properties reaches maximum; (2) Compared with the traditional processing agent ACR, adding hyperbranched polyester substantially does not affect the mechanical properties, but hyperbranched polyester has large advantage in the processing temperature to reduce plasticizing temperature of PVC; (3) Adding hyperbranched polyesters in PVC also can significantly reduce the viscosity of PVC, and the increasing amount of hyperbranched polyester is good for PVC processing.
