Abstract
A polymeric composition comprising a copolymer of ethylene with at least another monomer comprising at least a heteroatom, a tackifier, less than 10% of a compatible plasticizer or blend of plasticizers and a volatile material. The compositions are able to deliver effectively the volatile material incorporated for a long time and also have good adhesion properties on most substrates.
