Title:
AGRICULTURAL SOLID SILICONE COMPOSITION HAVING BIOLOGICAL ACTION
Document Type and Number:
Japanese Patent JPH02108606
Kind Code:
A
Abstract:
PURPOSE: To obtain the subject composition which is prepared by uniformly dispersing a water-soluble and agriculturally active substance in a water vapor- permeating silicone substance and can release the active substance in a non- liquid medium in zero-order kinetics. CONSTITUTION: An agriculturally active substance which is in a water-soluble form and has a biological action is dispersed in a at least partially crosslinked or non-crosslinked water vapor-permeable silicone substance in a proportion of 5-50 pts.vol., preferably 15-40 pts.vol. per 100 pts.vol of the silicone substance. The silicone substance is, for example, (A) a composition containing a diorganopolysiloxane rubber, a reinforcing extender and or an organic peroxide or (B) a thermally vulcanizable composition containing a diorganopolysiloxane rubber bearing 2 or more vinyl groups bonding to silicon atoms, an organopolysiloxane bearing 3 or more hydrogen atoms bonding to silicon atoms, a reinforcing extender and a metallic catalyst in the platinum group.
