A static mixer assembled on a Brabender plastograph has been used as a
blender of immiscible polymers like low-density polyethylene (LDPE) a
nd polyamide 6 (PA6). The shearing rates were 50 and 100 s(-1). The pr
operties of polymer blends were tested using a thermomechanical method
. It was found that a tested prototype static mixer imparted good unif
ormity to the blends' structure on a level similar to molecular distri
bution of components. This phenomenon is called mechanical compatibili
zation. High effectiveness of mixing was observed for LDPE-PA6 composi
tions with and without a compatibilizer. (C) 1997 John Wiley & Sons, I
