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.

Polymeric compositions for sustained release of volatile materials

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.

The present invention relates to liquid impermeable, moisture vapour permeable film or layers comprising thermoplastic hydrophilic polymeric compositions. The thermoplastic compositions comprise selected thermoplastic hydrophilic polymers, selected compatible plasticisers, and selected functionalized copolymers that provide the resulting film or layer with an increased mechanical strength, and better bonding capability to a substrate, without impairing the moisture vapour permeability of said films or layers. The layers and films of the present invention made from the thermoplastic hydrophilic polymeric compositions can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.

Liquid impermeable, moisture vapour permeable layers and films comprising thermoplastic hydrophilic polymeric compositions

Compositions comprising polytetramethylene glycol and a volatile material (e.g. a perfume) are able to sustainedly release said volatile material and are easy to disperse in liquid and cream products.
