A polymeric composition comprising a copolymer obtained from at least one monomer comprising an ether group and at least one monomer not comprising an ether group, a compatible plasticizer and a volatile material is able to provide sustained delivery of the volatile material over a long period of time. Additionally, if the volatile material is a composition formed by several components of different volatility, the compositions of the present invention is able to provide a uniform release of all components of the volatile material.
La présente invention se rapporte à une composition polymère comportant un copolymère obtenu à partir d'au moins un monomère comprenant un groupe éther et au moins un monomère ne comprenant pas de groupe éther, un plastifiant compatible et une matière volatile, ladite composition polymère permettant la libération prolongée de la matière volatile pendant une longue période de temps. En outre, si la matière volatile est une composition formée par plusieurs composants de volatilité différente, les compositions de la présente invention permettent d'assurer une libération uniforme de tous les composants de la matière volatile.
