Higher lignin contents have recently been shown to protect this polymer against thermal degradation, [ 15] as shown in Fig. 11.5, which illustrates the thermal degradation of PP-lignin blends as a function of the amount of... 

Homogeneous blends of PVA with 5-15 per cent of a KL modified by reaction with a maleimide-substituted aromatic carboxylic acid provided a means to improve the thermal and photochemical stability of the vinyl polymer [34]. Thus, the thermal resistance of the PVA-modified lignin blends increased, as illustrated in Rg. 11.8 [34]. Spectroscopic... 

Recent additions to these investigations deal with the use of poly(ethylene terephthalate) as the lignin blend component [69] and with the oxidative thermal stabilization of KL fibres [70].

In the case of the commercial PE/starch blends it has been established that the films were much affected by aqueous medium, while PO/lignin blend films undergo various molecular, macromolecular, and morphological changes, especially in soil [81],...

Poly(vinyl acetate)/lignin and poly(e-caprolactone)/lignin blends were prepared by casting chloroform solutions of PVAc (Mw 140 kDa) and PCL (Mw 80 kDa) mixtures containing 9-30% by weight of lignin (Table 2).
