1. A biodegradable controlled release agrochemical composition comprising a shaped agricultural active material that is at least partially water soluble which is encapsulated with a coating of a coating composition for controlled release of the agricultural active material,
wherein the coating composition comprises an adduct formed by chemical reaction of monomer A and monomer B,
wherein monomer A is selected from the group consisting of ethylene glycol bis(2-mercaptoacetate) (GDMA), trimethylolpropane tris(2-mercaptoacetate) (TM PTMA), pentaerythritol tetrakis(2-mercaptoacetate) (PETMA), pentaerythritol tetrakis(3-mercaptopropionate) (PETMP), trimethylolpropane tris(3-mercaptopropionate) (TMPTMP), ethylene glycol bis(3-mercaptopropionate) (GDMP) and any combination thereof,
wherein the monomer B comprises a component having between 2 and 50 ester groups and between 2 and 8 unsaturated carbon-carbon double bonds and having a molecular weight of between 200 and 5000 g/mole,
wherein the monomer B further comprises a cyclopentane and/or cyclohexane moiety, and
wherein the coating has a thickness between about 5 and 110 μm and/or wherein the amount of coating material applied is 1 to 20 parts per hundred (pph) by weight.
