  • USE OF BIOCOMPATIBLE POLYMERS FOR THE PREPARATION OF A COMPOSITION OR A MEDICAL DEVICE
    Publication number: 20140301972
    Abstract: The invention relates to a biocompatible polymer having general formula (I) AaXxYy, wherein: A denotes a monomer; X denotes an RCOOR? group; Y denotes an O or N-sulphonate group which is fixed to A and which has either formula —ROS03R? or —RNS03R? in which R denotes an optionally branched and/or unsaturated aliphatic hydrocarbon chain which can contain one or more aromatic rings and R? denotes a hydrogen atom or a cation; a denotes the number of monomers; x denotes the rate of substitution of the A monomers by the X groups; and y denotes the rate of substitution of the A monomers by the Y groups. More specifically, the invention relates to the use of said biocompatible polymers for the preparation of a pharmaceutical, dermatological or cosmetic composition or a medical device, which are intended to prevent, relieve and/or treat discomfort, distress, itches, irritations and/or pain and/or to protect tissues against same.
