Abstract

The present invention discloses a composition that may be extruded and/or injection moulded, comprising a chemically modified softwood lignin and a polyester. The chemically modified softwood lignin constitutes 2 to 45 weight-% of the total weight of the composition.

Claims (6)

1. A composition comprising a chemically modified softWood lignin and a polyester, Wherein - said chemically modified softWood lignin is carrying one or several O- 5 substituents being selected from substituents of Formula I-S and II-S, or mixtures thereof, - R being independently selected from C4-C25-alkyl, and 10 -.»f~*~.¿§----said polyester is selected from PBS (PolyButylene Succinate) and PBAT (PolyButylene Adipate Terephthalate) and said chemically modified softWood lignin constitutes 2 to 35 Wt-% of the total Weight of the composition;
2. A composition according to claim 1, Wherein said chemically modified softWood lignin is derived from a softWood lignin selected from a softWood kraft lignin (SWKL), a softWood organosolv lignin (SWOL) and a softWood 20 soda pulping lignin (SWSPL).
3. A composition according to claim 1 or 2, Wherein essentially the rest of the total Weight of said composition, beside said chemically modified softWood lignin, being said polyester.
4. A product being extruded and/ or injection moulded and comprising said composition according to any one of claims 1 to
5. A method of extruding said composition according to any one of claimsto 3, comprising the steps of: -mixing said chemically modified softWood lignin and said polyester and optionally a compatibilizer, to form a miXture; -extruding said mixture at a temperature of at least 100°C to form an eXtruded material; -optionally cutting said extruded material into pellets; and -optionally drying said extruded material.
6. A method of injection moulding said composition according to any one of claims 1 to 3, comprising the steps of: -providing pellets or powder of said composition; and -injection moulding said pellets or powder into a desired shape at a temperature of at least 100°C.
