Abstract: A polymeric material, in particular a polymeric material manufactured by polymerisation or polyaddition, for example polyolefins or polyurethanes, in particular polyethylene, with an antimicrobial surface. The polymeric material contains a maximum of 0.1% by weight of fatty acid ester, a maximum of 0.1% by weight of superacid counter-ions and between 2.5% by weight and a maximum of 10% by weight, preferably a maximum of 5% by weight, of at least one compound (1) which brings about the antimicrobial action. This compound (1) consists of at least one antimicrobially effective hydrophilic molecular group (2) and at least one molecular group (4) which causes physical anchoring of the compound (1) in the polymeric material (3).

Abstract: The present invention relates to coatings comprising a matrix and an active polymer embedded therein, characterised in that either (i) the matrix is cross-linked, or (ii) the active polymer is cross-linked or (iii) the active polymer is covalently bonded to the matrix; and in case of a cross-linked active polymer a matrix may be omitted; and the active polymer contains structural units according to the description, and a cross-linking agent and/or coupling reagent are optionally contained therein. Said coatings exhibit outstanding anti-ice properties. The invention further relates to shaped articles and devices comprising such coatings, and to a method for the manufacturing and the use of such coatings, shaped articles and devices.

Abstract: The present invention relates to substrates comprising an outer functional layer characterized in that said layer possesses functional groups of formula (I), wherein the substituents are as defined in the specification; freezing point reducing surfaces, particularly surfaces which by application of a specific layer provide a freezing point reducing effect; further compounds suitable to establish such surfaces; devices comprising such surfaces; methods for manufacturing such compounds; surfaces and devices as well as the use of said compounds and surfaces in various applications.
