Abstract: A laminate with a decorative layer over an electrical functional layer such as a touch sensor panel, which provides for example a touchpad functionality, as well as a production method for it. It is possible for the first time to perform an individualization of prefabricated laminates with functionality such as touch functionality of a touch sensor in an uncomplicated manner. This is achieved by supplementing a functional laminate with a laser protective layer between the electrical functional layer and a decorative layer which can be lasered and written on with simple measures.

Abstract: The invention relates to a novel synthesis process in order to produce meltable PAN copolymers with increased thermal stability. The PAN copolymers produced using the method according to the invention surprisingly exhibit improved thermal and mechanical properties compared to PAN copolymers produced using methods known from the prior art. The invention additionally relates to corresponding PAN copolymers and to molded bodies produced therefrom or to a method for producing such molded bodies, in particular melt-spun mono- or mufti-filaments.

Abstract: The invention relates to a method for the production of thermally stabilised melt spun fibres, in which polyacrylonitrile (PAN) fibres or PAN fibre precursors produced by melt spinning are treated in an aqueous alkaline solution which comprises in addition a solvent for PAN. Likewise, the invention relates to fibres which are producible according to this method.

Abstract: The invention relates to melt spinnable copolymers of polyacrylonitrile (PAN) which are producible by means of copolymerisation of acrylonitrile with an alkoxyalkylacrylate. As additional comonomers alkylacrylates and vinyl esters may be considered. Likewise, the invention relates to a method for the production of fibres or fibre precursors, in particular carbon fibre precursors, by means of melt spinning, in which the mentioned copolymer is used. Furthermore, the invention relates to fibres produced in this way, in particular carbon fibres.

Abstract: The present invention relates to a process for preparing a polymer dispersion comprising polymerising one or more water soluble anionic monomers (m1) and one or more non-ionic vinyl monomers (m2) present in a reaction mixture further comprising a polymeric stabiliser (B) and a polymeric co-stabiliser (C). It further relates to a polymer dispersion, the use of the polymer dispersion and a process for producing paper.
