Abstract

Microcapsules of glyphosate were made by the method of in-situ polymerization with urea-formaldehyde resin as the outer membrane. The effects of reaction parameters on particle size, distribution and structure were studied. Encapsulation efficiency and controlled release were characterized. Optimal reaction conditions were as follows: acidification time being 4 h, endpoint pH being 2.0, curing temperature being 70 ℃, curing time being 2 h, mixing rate being 2 000 r·min-1, acid catalyst being NH4Cl and suitable emulsion being styrene maleic anhydride(SMA). Under those conditions, solid, spherical microcapsules were formed with decentralization of 1-10 μm, the encapsulation efficiency was 91.9% and it had excellent controlled release properties. These results suggested that the microcapsules could fully meet the needs of practical applications.
