The thermal degradation of wood flour occurs over a wide
temperature range in both oxygen (250–430 ◦C) and nitrogen
atmosphere (250–600 ◦C). But in contrast to the PP-copolymer,
some mass loss of wood flour in nitrogen occurs in the temperature
regions between 25 ◦C and 150 ◦C, 150 ◦C and 250 ◦C and
between 400 ◦C and 600 ◦C while the mass loss of the PP-copolymer
occurs mainly between 300 ◦C and 500 ◦C. Wood degradation in th
