摘要：
The present invention pertains to a copolymer obtained by reacting a mixture of acrylonitrile or of a mixture of acrylonitrile and an organic molecule that can be copolymerized with acrylonitrile, with which a monomeric, oligomeric and/or polymeric silazane can be obtained, said silazane containing at least one vinylic double bond. The copolymer can be brought into fiber form and/or made infusible. The production of ceramic fibers by pyrolysis is possible with fiber-like copolymers.
