摘要：
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.
