Dendrimers as thermoplastic toughening agents have great ...

Dendrimers (CYD-PR121/CYD-PR2 56/CYD-PV121/CYD-P V256) as toughening agents for thermosetting material (bismaleimide BMI) have the following advantages: low viscosity, can reduce the processing viscosity of BMI system, ease of processing, more easily compatible with BMI. Methods: Acetylating its active end group by modification, to avoid its reaction with BMI system. BMI + HBP dissolved in allyl phenol solvent, and then stirred and heated to 145 ℃, the clear homogeneous solution was prepared, degassed and added to the preheated mold to solidify, 150 ° C (5 h), 200 ° C (3 h), 250 ° C (3 h). When the dosage of dendrimer is 9%, elongation at break can reach the maximum of 138%, toughening performance was increased by 15.9% compared with linear polyesters, meanwhile, system without dendritic polymers as toughening agent, the elongation at break could not be determined, thus no toughness.

Dendrimer-based glyphosate has better performance.

Dendrimer-based novel formulations of glyphosate has better pesticide effect than commercially available glyphosate, the advantage is to improve the solubility, increase dispersion, protect active substances, increase adhesion and so on. Even under adverse conditions are valid, such as under rainfall conditions, efficacy is still improved by 150% -250%. Nufarm and Starpharma cooperated together to do R & D, produce dendrimer-based substrate to increase or decrease the flow of insecticide penetration-imidac loprid-underground insects, efficient dendrimer-based crop protection products have become the R & D focus of international pesticide manufacturers, and there are always new international patent applications generated. Weihai CY Dendrimer Technology Co. Ltd as the first company in Asia to R&D and produce dendrimers, we have provided many dendrimer products to Peking University, Tsinghua University and Chinese Academy of Sciences, etc. for scientific experiments, and now we have already realized the industrialization of dendrimers. Welcome to the manufacturers of pesticides and other agricultural products to use our dendrimers in efficient crops product development and production to improve performance.

Application of dendrimers in slow release pesticide

Compared with ordinary pesticide, slow release pesticide with dendrimers have following advantages: 1) solubility to decrease dosage 2) reduce pesticide loss in the environment to enchance the utilizatioin ratio 3) increase adhesion and retention of pesticide on plants, prolong retention time 4) Increase penetration to the plants and insects to improve pesticide effect 5)Contr ol pesticide release speed to have functional and energy saving pesticide 6)Long term effect by one time usage 7) Resistance to rain, weather and improve environmental stability Example as following: Dendritic polymers were used as pesticide carriers to mix with dichlorophenoxyace tic acid (2,4-D). The result showed dendritic polymers can well coat herbicide 2,4-D. Further crop experiments showed that the pesticide with dendritic polymers as carriers had good slow release performance. Compared with the traditional pesticide,the dendritic pesticide performance was increased by 2-4 times, and had excellent resistance to rain, weather and other environmental. The slow release pesticide can be controlled at slowed-release period and release time can be increased up to 1-3 months. Weihai CY Dendrimer Technology Co.

Superior performance of dendrimers based pesticide compos...

Dendrimer-based pesticide composition is a amphipathic substance (hydrophilic group and a hydrophobic group), the composition is in the form of concentrate, when being diluted with water, it forms small particles (micelles). Compared to the previous compositions, the insecticidal properties of the composition has been significantly improved, as in the control of pests, bioavailability, and other soil mobility, the composition can control the pests. Thus, pesticide compositions can be combined with one or more of the active ingredient, or different compound, to improve bioavailability of pesticides or pesticide formulations, reduce metabolism, reduce toxicity, increased chemical or photochemical stability, increase soil mobility.Weihai CY Dendrimer Technology Co.
