Abstract

1,2‐dihydroxysubstituted poly(p‐xylylene)s were synthesized in the presence of samarium(II)‐iodide. The structure and endgroups of the polymers were verified by spectroscopy and chromatography. The structure—property relationships of the poly‐1,2‐diol structures obtained were investigated. Polymer analogous transformations were carried out for poly‐(1,4‐phenylene‐1,2‐ethanediol). The reaction parameters were investigated with respect to degrees of polymerization. Although some of the polymers were soluble, precipitation was found to be the reason for limited molecular weights.
