## Abstract Stereospecific polymerization of styrene was catalyzed by homogeneous neodymium phosphonate [Nd(P~507~)~3~]βH~2~OβAl(iβBu)~3~ catalytic system. The polymer was separated into isotactic polystyrene and atactic polystyrene by extracting the latter with boiling 2βbutanone. The conversion o
