Abstract
Stabilized liquid cyclopropane compositions are provided which compromise flowable, non-aqueous dispersion concentrates comprising a) a continuous substantially water-immiscible liquid phase and b) a dispersed solid phase comprising cured polymer particles prepared from a polymerizable thermoset resin which particles contain at least one cylcopropene complex, optionally a non-porous particulate mineral, and optionally a non-cross-linkable mobile chemical distributed therein, and wherein the outside surfaces of the particles comprise a colloidal solid material. The compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.
Claims27
A polymer particle, comprising:
- a body formed from a polymerizable resin;
- an alkyl-cyclopropene and a molecular encapsulating agent complex dispersed within the body;
- and
- a colloidal solid embedded within the body.
A process for making a non-aqueous liquid dispersion concentrate incorporating a cyclopropene complex comprising the steps of
- a dissolving or suspending the cyclopropene complex in a non-aqueous liquid mixture comprising at least one curable thermoset resin, optionally at least one non-cross-linkable mobile chemical and optionally at least one non-porous particulate mineral;
- b. emulsifying said solution or suspension in a water-immiscible liquid containing a colloidal solid emulsion stabilizer;
- and
- c. effecting cure of the at least one curable thermoset resin mixture to produce a dispersion of polymer particles which contain a cyclopropene complex in a water immiscible liquid.
