Abstract
Official abstract text for this publication.
Skin-contact products with a transpiration function such as medical devices or medicinal products, of which face masks, aspirators, ventilators, breast pumps or wound dressings are examples are described especially a skin-contact product with a transpiration function with an improved microclimate at a patient interface material-skin contact area. In an embodiment a material system is described that comprises a hydrophobic silicone base material and a hydrophilic silicone material that is combined with the hydrophobic base material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymerizable composition comprising: (a) a hydrophobic organic monomer or pre-polymer, (b) a hydrophilic monomer being an alkenyl sulfonate having 3 to 28 carbon atoms in association with a cation, and (c) a ligating compound for said hydrophilic monomer (b) in an amount sufficient to dissolve the cation and achieve solubility or miscibility of said hydrophilic monomer (b) in said hydrophobic organic monomer or pre-polymer (a), wherein said composition yields a rubbery or elastomeric polymer material taking up more than 5% by weight of water and up to 500% by weight of water after immersion in demineralized water at room temperature for a sufficient time to reach saturation. 2. A polymerizable composition according to claim 1 , wherein said hydrophilic monomer (b) reacts or associates with said ligating compound (c) and wherein, after reaction or association with said ligating compound (c), is able to react with said hydrophobic organic monomer or pre-polymer (a) under liquid phase polymerization conditions wherein said hydrophilic monomer (b) is incorporated into the polymer sequence resulting from liquid phase polymerization of said hydrophobic organic monomer or pre-polymer (a). 3. A polymerizable composition according to claim 1 , wherein said ligating compound is selected from the group consisting of a crown ether, a cryptand and a calixarene.
