Abstract
Stabilized liquid cyclopropene compositions are provided which comprise 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 cyclopropene 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.

A non-aqueous liquid dispersion concentrate composition comprising
- (a) a continuous substantially water-immiscible, non-aqueous liquid phase which is selected from the group consisting of vegetable oils, silicone oils, methylated vegetable oils, refined paraffinic hydrocarbons, mineral oils, and mixtures thereof;
- (b) a dispersed solid phase comprising polymer particles having a complex of α-cyclodextrin and 1-methylcyclopropene distributed therein prepared from:
- (i) dissolving or suspending the α-cyclodextrin 1-methylcyclopropene complex in a nonaqueous curable liquid mixture comprising a curable or polymerizable thermoset epoxy
- (ii) emulsifying said solution or suspension into a water-immiscible, non-aqueous liquid to a mean droplet size of 1-200 microns, which liquid also contains a colloidal solid emulsion stabilizer, and
- (iii) effecting crosslinking, polymerization or cure of the curable or polymerizable thermoset epoxy resin mixture to produce the dispersed polymer particles having the α-cyclodextrin 1-methylcyclopropene complex distributed therein.
A non-aqueous liquid dispersion concentrate composition, comprising:
- 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;
- and
- a continuous substantially water-immiscible, non-aqueous liquid phase which is selected from the group consisting of vegetable oils, silicone oils, methylated vegetable oils, refined paraffinic hydrocarbons, mineral oils, and mixtures thereof.
