ABSTRACT:
This present invention provides aqueous emulsions which are capable of depositing coatings and membranes of hydrophilic, water-absorbing silicone-organic polymer elastomers. The elastomers are free radical polymerized copolymers of (A) from 50 to 95 parts by weight of block copolymers containing polydiorganosiloxane segments and polyalkyleneoxy segments which block copolymers contain terminal aliphatically unsaturated groups such as those derived from the reaction of isocyanatoethyl methacrylate with terminal free hydroxyl groups present on the polyalkyleneoxy segments and (B) from 5 to 50 parts by weight of at least one substantially water insoluble aliphatically unsaturated organic monomer which is compatible with (A) such as methyl methacrylate. The aqueous emulsions are useful for forming coatings and membranes of the above elastomers and also provide a vehicle for the deposition of coatings of such elastomers which are capable of controllably releasing bioactive agents such as insecticides or herbicides which are dispersed within the elastomer film deposited from the aqueous emulsion.
