| titleOfInvention | Membrane containing liquid active material and production thereof |
| abstract | PURPOSE: To produce a membrane having a liquid active material, which can release the liquid active material at a constant rate over a long period of time, by coating the surface of a support with a soln. obtd. by dissolving a polymer and an active material, which is a liquid at room temp., in a specified org. solvent and then evaporating the solvent. n CONSTITUTION: At least 30wt% polymer (A) such as PS and not more than 70wt% active material (B) (e.g. diazinon), which is a liquid at room temp. and has a solubility of not more than 5pts.wt. per 100pts.wt. polymer at room temp., are dissolved in an org. solvent (e.g. chloroform) in such a proportion as to give a concn. of 10W40wt% in term s of the combined quantity of components A and B, said solvent being capable of dissolving components A and B and being more volatile than component B. The resulting soln. is applied to the surface of a support in a coating thickness of 10W50μ and evaporated by heating at 0W100°C, but at a temp. not higher than the b.p. of the solvent in an atmosphere having humidity of 60% or above to form a polymer layer in which component B in the formh of liquid droplet is enclosed in a lot of micropores which have a pore size of 0.5W10μ and are divided by a partition wall of 0.5W10μ in thickness. n COPYRIGHT: (C)1984,JPO&Japio |
