Abstract: A multi-layered laminate for producing membranes for electroacoustic transducers, comprises a first layer of a polyether ether ketone film having a heat of crystallisation of at least 15 J/g, a second layer (of a thermoplastic plastic film having a heat of crystallisation of no more than 5 J/g, and an adhesive layer arranged between the first and second layers. Alternatively, the first and second layers are defined by their shrinkage properties after 15 minutes at 200° C.: the first layer has shrinkage of more than 10% in at least one direction, and the second layer has shrinkage of less than 10% in the longitudinal and transverse directions. A laminate constructed in this manner exhibits lower fold formation when processed using multi-cavity thermoforming. The laminates are useful for the production of membranes for electroacoustic transducers.

Abstract: The intention is to provide powerful pressure sensitive adhesives with high adhesion and adjustable cohesive failure characteristics. This is accomplished with pressure sensitive adhesives which comprise 30-90 wt % of at least one poly(meth)acrylate; 10-60 wt % of three-dimensional bodies K made from an inorganic material with a maximum extent of 40 to 300 μm; and 0.1-10 wt % of at least partly expanded microballoons M, based in each case on the total weight of the pressure sensitive adhesive. Another subject of the invention is an adhesive tape which comprises a pressure sensitive adhesive of this kind.

Abstract: The invention relates to bio-based polymer based on at least two different bio-based monomers obtained from biomass-containing carbohydrates, wherein at least one bio-based monomer is a furan derivative according to formula (I). In each case, independently of one another, R1 is a hydrogen or an organofunctional group with 1 to 20 C atoms and optionally, the organofunctional group contains O, N, or S atoms; R2 is an organofunctional group with 1 to 20 C atoms, which optionally contains O, N, or S atoms, the second bio-based monomer is a hydroxyl-functional compound comprising from 1 to 100 C atoms. The polymer has an average molecular weight Mw greater than or equal to 1,000 g/mol, and the proportion of bio-based monomers in the bio-based polymer is greater than or equal to 55 mol-% with respect to all monomers of the polymer.
