Dendrimers have superior performances as a new class of toughener.
Using a certain dosage of dendrimers(CYD-CD215/CYD-CR111/CYD-CV111) to modify epoxy resin, while improving the toughness, the strength remained unchanged.When dendrimer dosage is 16%, bending performance reaches maximum, bending strength improved from 55. 37 MPa to 60. 32MPa, bending modulus improved from 3544. 89 MPa to 3758. 32MPa, meanwhile impact strength reaches maximum, from 3. 10 kJ /m2 to 4. 64 kJ /m2, improved almost 50%.

Excellent performances of dendrimers for the controlled release fertilizers.
The main problem of controlled release fertilizer on the market is that the brittleness increased after sulfur solidification, causing sulfur coated controlled release fertilizer seriously unshell. In existing production processes, coat the outer membrane of sulfur with thermosetting resin, microcrystalline wax or epoxy eased the problem, but there are still shelling phenomenon, affecting the release fertilizer effect. Dendritic polymer (CYD-CR236/CYD-CR486/CYD-CV236/CYD-CV486) used as toughening agent has very distinct advantages: 1) the effect is obvious, the impact strength and tensile
