In situformation and compounding of polyamide 12 by reactive extrusion

Autor: A. Wollny, H. Faulhammer, Rolf Mülhaupt, N. Hoogen, Hansjörg Nitz

Publikováno v: Journal of Applied Polymer Science. 90:344-351

The anionic polymerization of lauryllactam was initiated at 270°C using sodium hydride as an initiator and N,N′-ethylene-bisstearamide (EBS) as an activator (NaH:EBS molar ratio of 2). Polymerization occurred in less than 2 min and was successfull

Reactive extrusion of polycaprolactone compounds containing wood flour and lignin

Autor: Hinnerk Semke, Rolf Mülhaupt, Rüdiger Landers, Hansjörg Nitz

Publikováno v: Journal of Applied Polymer Science. 81:1972-1984

Biodegradable polycaprolactone (PCL) was melt-compounded in a Werner & Pfleiderer twin-screw extruder (ZSK25) together with wood flour (WF) and lignin with maleic anhydride-grafted polycaprolactone (PCL-g-MA) used as a compatibilizer. The grafting of

Influence of compatibilizers on the surface hardness, water uptake and the mechanical properties of poly(propylene) wood flour composites prepared by reactive extrusion

Autor: Peter Reichert, Hansjörg Nitz, Hartmut Römling, Rolf Mülhaupt

Publikováno v: Macromolecular Materials and Engineering. :51-58

Anisotropic wood flour (WF) particles, composed of fiber bundles, were melt compounded in a twin screw extruder at 200°C together with poly(propylene) (PP) in the presence of maleic anhydride-grafted poly(propylene) (PP-g-MA) and maleic anhydride-gr

Influence of Lignin Type on the Mechanical Properties of Lignin Based Compounds

Autor: Hinnerk Semke, Rolf Mülhaupt, Hansjörg Nitz

Publikováno v: Macromolecular Materials and Engineering. 286:737

Several types of sulfur-free lignins were melt compounded in a Werner & Pfleiferer twin screw extruder (ZSK 25) together with polyamide 11 (PA11), a bio-degradable polyester (Ecoflex®) and a biodegradable poly-esteramide (BAK®). Sulfur-free lignins
