The synthesis of poly (p-xylylidene) from p-xylylene dichloride by solution method using potassium t-butoxide in DMSO, and by phase-transfer catalyst method using tetra-n-butylammonium chloride was investigated. The latter method gave the polymer in a good yield, which contained a small amount of ether linkage in the main chain. This polymer showed a poorer thermal stability than the polymer obtained by solution method. Poly (p-xylylidene) derivatives containing chlorine or nitro group in the aromatic ring and sulfonyl or carbonyl group in the main chain were also prepared from the corresponding substituted p-xylylene dichloride by solution method. All the polymers except one containing nitro group started decomposing at ca. 340°C. Thus the substituted groups in the polymer scarcely affected the thermal stability of the polymers.
