Document Type and Number:
WIPO Patent Application WO/2013/069701
Kind Code:
A1
Abstract:
Provided is a water-dispersible vaporized active substance sustained release product which is capable of releasing almost the entire quanity thereof at a constant release rate over a long period of time, and which has a low viscosity and adequate adhesion performance. In concrete terms, provided is a water dispersion for a sustained release product, containing: polymer particles obtained by polymerizing an ethylenic unsaturated group-containing monomer (A); polyvinyl alcohol (C2) having a degree of saponification that exceeds 91.5mol.% but is less than 98mol.% and which is contained in a quantity of more than 0 but not more than 50mass% with respect to the total quantity of said ethylenic unsaturated group-containing monomer (A); and water. Viscosity at 25°C does not exceed 100mPa⋅s. Also provided is a sustained release product containing this water dispersion and a vaporized active substance selected from a group consisting of pheromone substances, agricultural chemicals, fragrances, deodorizing agents and antibacterial agents.
