• 1. Hyperbranched polyester modified epoxy resin has excellent
performances. Hyperbranched polymer has low viscosity, high functionality,
no chain entanglement and good solubility characteristics, provides a new
way for epoxy toughening. Modifying the hydroxyl-terminated hyperbranched
polyester (AHBP) obtained hyperbranched polyester with carboxyl end group
(CHBP), not only has the toughening effect, but also play the role of a curing
agent. Using CHBP as flexibilizer and curing agent, study its toughing effect
on epoxy/MTHPA (EP/MeTHPA) curing system; CHBP molecular terminal all
with carboxyl has the best toughening effect, impact strength achieves 18.5
kJ/m2; when the carboxyl terminal content reaches 40%, the impact strength
of the epoxy resin is only 7.8 kJ/m, CHBP has no toughening effect at this
time. When CHBP mass fraction is 15%, tensile strength achieves the
maximum , 64.86 Mpa; when CHBP mass fraction is 15%, the Tg of the
resulting cured epoxy resin is 106 , increased about 6 . Weihai CY℃ ℃

• 2. Effective application of hyperbranched polyester in UV curable coatings
industry.The development of UV-curable coatings is faster and faster, as
people's awareness of environmental protection, research of low VOC
emissions, high-performance UV coatings is on the agenda, hyperbranched
polyester due to its low viscosity, multi-functional groups can be used as
toughening or curing agents for coatings industry. Through the terminal-
modified of hyperbranched polyesters , introducing appropriate group such as
double bond, aliphatic chains, it can be used as UV curable monomer ,and
obtain a better film properties, with suitable thermal stability (300 high℃
temperature resistant) and the glass transition temperature (60 or so), the℃
system’s toughness and hardness are increased, the tensile strength
achieves 10MPa. Weihai CY Dendrimer Technology Co. Ltd forwards from

• 3.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.

• 4.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. Weihai CY Dendrimer Technology Co. Ltd forwards from

• 5. 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. Weihai CY Dendrimer
