Phenylacetylene was polymerized with WOCl,/tetraphenyltin (mole ratio 1 : 2) catalyst in benzene and benzene/ 1 ,4-dioxane mixtures. The resulting polymers were characterized by means of multidetector size-exclusion chromatography and ' H NMR and IR spectroscopy. 1,4-Dioxane used as a co-solvent was
## Abstract **Summary:** Magnetic field dependence of poly(phenylacetylene) (PPA) that has been stereoregularly prepared with a Rh complex catalyst was investigated in detail between 2 K and 300 K. The data showed a spin glass‐like magnetic behavior, i.e., two cusps were clearly observed when PPA w
