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.

Effective application of Hyperbranched polymer in plastic (PA and HDPE) processing.
(1) hyperbranched polymer had no significant effect on the HDPE melt temperature and the crystal , crystallization temperature and the crystallinity increased slightly; (2) hyperbranched polymer can improve the HDPE melt flow, HDPE / HBP blends remains pseudoplastic fluid, it can reduce the melt complex viscosity, injection molding experiments show that hyperbranched polymers can significantly reduce the HDPE injection molding processing temperature, thus improving its processing performance and reduce energy consumption; (3) hyperbranched polymer can improve HDPE extrusion melt fracture, improve extrusion surface smoothness; (4) hyperbranched polymer in HDPE can be 150-250nm scale dispersion, though are not up to the molecular level dispersion, but making HDPE tensile strength increased, when dosage is 0.18% , it can be improved by 26.16%.

Effective application of dendrimer in carbon dioxide catalytic reactions.
(1) through "divergent synthetic method," using KH550 to modify amino groups of silica and react with acrylate, diamines series, then obtain silica with PAMAM on the surface; (2) the synthetic silica with branch phosphine composes catalyst system with RuCl3, to verify the catalytic activity in the catalytic hydrogenation reaction of carbon dioxide, the catalytic activity of 1-4G increased with the increase of generation, the activity of 4G reaches maximum(TOF: 4195) ,5-6G activity decreases.
