Reaktionsschritte
PHA pellets were compounded from formulations based on BIOPOL powder of Mw=895k, 0.1 phr DZB (cyclohexylphosphonic acid), 0.4 phr ZnSt (zinc stearate) and 10 phr ATC plasticizer. Plasticizer were determined at 170 C and 5 kg load. The powder blends prepared in a Pappenmeier high speed blender were fed in a Betol single screw extruder, using the conditions summarized in Tables 1 and 4. BIOPOL, pellets with Mw of 727k were obtained with output from 3.0 kg/hr at a screw speed of 40 rpm. The following results were obtained:
