An acrylate copolymer for use in pressure-sensitive adhesives, particularly suitable for the bonding of low-energy surfaces, is composed of the following monomer components: A) 60 to 95% by weight of one or more monomers selected from alkyl acrylates and alkyl methacrylates, the alkyl containing 1 to 10 carbon atoms; B) 5 to 15% by weight of one or more monomers selected from esters of (meth)acrylic acid with a polyethylene glycol derivative having from 2 to 4 ethylene glycol units, the (meth)acrylic esters being free from hydroxyl groups; and C) 1 to 35% by weight of a mixture of at least two vinyl compounds selected from vinyl compounds which contain one or more of the following functional groups: free carbonyl groups, free carboxyl groups, groups having one or more active hydrogen atoms.

Medical pressure-sensitive adhesives with high permeability to water vapor and high adhesive force, and plasters provided therewith

Medical pressure-sensitive adhesive mass having a high moisture vapor

Medical patch material and a process for its production

The invention relates to a wound secretion absorbing hydrogel of the following composition:

Cross-linked hydrogels and their use as wound dressings

The invention relates to plasters, particularly epicutaneous test plasters with at least one active substance absorbing or receiving device (14) arranged on a carrier film (32). The carrier film (12) is made from a highly elastic polymer material, which is impermeable for liquid water, but permeable for water vapour. On the surface remote from the skin, it is detachably connected in whole-area or partial area manner with a support film (11) at least covering the surface of the carrier film. The invention also relates to processes for the production thereof and the use thereof.
