Lignin-Modified Thermoplastic Materials - ScienceDirect

Jan 01 2019 The lignin-modified by caprolactone can increase its polarity and get an asteriod graft copolymer. Therefore the composite produced by blending caprolactone-modified lignin with PVC will show a good compatibility between the components while the composite also has a single T g that meets the Fox equation.【Get Price】

Modified Lignin - an overview | ScienceDirect Topics

This chapter focuses on lignin-modified materials including the most widely applied lignin-modified materials: rubber engineering plastics adhesives and three other materials. Lignin as a filler instead of carbon black to modify rubber can enhance the mechanical properties of rubbers while also improving the oxidation resistance and solvent resistance of the matrix.【Get Price】

[PDF]PREPARATION OF A LIGNIN-BASED COMPOSITE AND ITS …

70%. The effects of pressure temperature and the modified lignin dosage on the properties of the composites were also evaluated. The pressure of 2 MPa was not enough to make a strong composite and the composite with low dosage of modified lignin could not resist water which signifies pressure and the ratio of modified lignin to sawdust are【Get Price】
