The morphological evolution of as-grown poly(phenylacetylene) (PPA) free standing films has been studied. Investigations performed by scanning electron microscopy show that the freshly prepared PPA films exhibit a glass-like morphology which subsequently evolves into a microsphere structure. After ageing for 3 months at room temperature, PPA films reach a stable enamel-like phase. The chemical structure of the Rh(I) catalysts does not appear to influence the morphology of PPA. However, different catalysts yield different rates of morphological evolution
