Title:
GEL-LIKE MATERIAL IN A PLANAR FORM FOR THE TREATMENT OF AMBIENT AIR
Document Type and Number:
WIPO Patent Application WO2005016392
Kind Code:
A9
Abstract:
The invention relates to a gel-like material in a planar form for treating ambient air. Said gel-like material contains a matrix comprising crosslinked polymers which are provided with hydrophilic groups and to which volatile active substances are adsorbed. The matrix forms a spongy structure along with said volatile active substances, from which the active substances are slowly and steadily released so as to react with and eliminate malodorous or harmful substances contained in the air. The polymer matrix comprises at least two different polymers which form an interpenetrating network, preferably after being crosslinked.
