COMPOSITIONS AND METHODS FOR IMPROVING FLOWABILITY OF SUPERABSORBENT POLYMERS

NºPublicación: WO2022165418A1 04/08/2022

Solicitante:

KANNAR EARTH SCIENCE LTD [US]

Resumen de: WO2022165418A1

A method includes mixing a dry hydrophobic material with a dry superabsorbent polymer to improve the flowability of the polymer in humid conditions within a machine passageway having a residency time. The application of superabsorbent polymers in agriculture is desirable to aid plant growth in increasingly hot and dry conditions. However, dry bulk planting applications typically used in agriculture require the dry amendment to pass through confined channels and narrow pores. This is problematic because the polymers rapidly absorb moisture from the environment and adhere to the planting equipment causing fouling and clogging. The improvement in flowability provided by the compositions disclosed herein, is to the extent that the superabsorbent starch-like polymer can be applied using dry bulk planting applications in the humid conditions of Florida in the springtime. Surprisingly, the dry mixtures improve flowability without undermining the ability of the polymers to rapidly absorb moisture from rain.
