Abstract: Methods for producing an adhesive filament from a pressure-sensitive adhesive, devices for carrying out the methods, adhesive filaments, adhesive rollers, and printed elements are provided. The methods comprise providing the pressure-sensitive adhesive; forming the pressure-sensitive adhesive to a material strand and treating at least a partial region of the surface of the material strand with a plasma stream.

Abstract: Deep-drawn membranes formed of polyester or polycarbonate films, comprising units of Formula (I) and (II), useful for acoustic signal converters as microphones and speakers. The film can be produced by thermoplastic processes or solvent cast processes.

Abstract: Films and membranes produced therefrom for acoustic signal converters made of polyester comprising the structural unit of formula (I) wherein R1 and R2 independently represent hydrogen, halogen, C1-C8 alkyl, C5-C6 cycloalkyl, C6-C10 aryl, C7-C12 aralkyl and R3 corresponds to a carbonyl group or to the formula (A)

Abstract: Use of an organopolysiloxane/polyurea block copolymer according to formula (1), where R is a univalent hydrocarbon radical with 1 to 20 carbon atoms, optionally substituted by fluorine or chlorine, X is an alkylene radical with 1 to 20 carbon atoms in which methylene units that are not adjacent to one another can be replaced by —O— groups, or is an arylene radical en with 6 to 22 carbon atoms, A is an oxygen atom or an —NR?— amino group, R? is water or an alkyl radical with 1 to 10 carbon atoms, Y is a bivalent hydrocarbon radical with 1 to 20 carbon atoms, optionally substituted by fluorine or chlorine, B and B? are a reactive or non-reactive end group that is bonded covalently to the polymer, n is a number from 1 to 4000 and a is a number starting from at least 10, as a coating on a pre-treated plastic surface, the polar surface energy fraction thereof being at least twice that of the untreated plastic surface.
