    摘要: A fusible lignin has a gas transition temperature in the range between 90 and 160° C. determined using differential scanning calorimetry (DSC), a molar mass distribution with a dispersivity of less than 28, determined using gel permeation chromatography (GPC), an ash content of less than 1 wt. %, and a proportion of volatile components of a maximum of 1 wt. %. Also provided is a precursor fiber based on the fusible lignin, as well as a method for the production thereof Also provided is a method for producing a carbon fiber from the precursor fiber.
