Abstract: A curable composition comprising a compound (A) having at least one active energy ray curable polymerizable functional group, a fluorine-containing copolymer (B) obtained by (1) copolymerizing a polymerizable monomer (a) having a polyfluoroalkyl group and a polymerizable monomer (b) having a photo-curable functional group, or (2) introducing a photo-curable functional group into a fluorine-containing copolymer (D) obtained by copolymerizing a polymerizable monomer (a) having a polyfluoroalkyl group and a polymerizable monomer (d) having a group capable of introducing a photo-curable functional group, and a photopolymerization initiator.

Abstract: Methods of making and using starch graft copolymers produce particle sizes useful in granule applicators for applying to agricultural fields. Starch graft copolymers on field crops provide excellent anti-crusting properties, increased seed germination and stand, increased crop growth, increased crop yields and reduced water requirements.
