Hyperbranched polyester as toughening agent of epoxy resin systems has good performance
Non-reactive hydroxyl-terminated hyperbranched polyesters can be used as toughening agent of epoxy resin system (bisphenol A epoxy resin) , which in the form of monodisperse particles disperse in epoxy matrix, play a toughening effect. When the dosage is 10%, it can obviously improve the impact resistance properties and is 2 times than without it. Hyperbranched polyesters in the form of particles disperse in the epoxy systems can reduce crack and play an enhanced effect. Weihai CY Dendrimer Technology Co.

2.With hyperbranched polyester coating can cure at 70 ℃ low temperature.
Double bond modified hyperbranched polyester can overcome the defect that general powder coating cure at 120 , it can achieve about 70 ℃ low temperature curing, thereby expanding the application of powder coatings, it is not limited to metal substrate, the heat-sensitive substrate (such as wood, plastic, etc.) applications, it has fast curing rate at low-temperature, high conversion rate, curing enthalpy is 70KJ/mol, compared to the curing enthalpy of methacrylic acid 57KJ/mol, it has obvious application advantages.Weihai CY Dendrimer Technology Co.

Dendritic polymers can greatly improve PP/ PVC performance.
(1) the dosage of PP-HBP is 5 units, PP / PVC / PP-H BP blending system tensile strength and impact strength reaches the maximum, respectively increase 18.03% and 28.2%; (2) PP-HBP improve PP/PVC compatibility of blends; (3) when PP-HBP dosage less than 5 units, PP/PVC/ PPHBP apparent viscosity of the blends is larger than PP / PVC blends; when PP-HBP dosage more than 5 units, PP/PVC/PP-HBP the apparent viscosity of blends is smaller than PP/PVC blends; (4) blends meet the free volume theory of polymer melt flow. With temperature increasing, the apparent viscosity of the blend decreases. Weihai CY Dendrimer Technology Co.
