<jats:title>Abstract</jats:title><jats:p>Polyferrocenylenes with mean molecular weights of 500–4 000 have been converted into thermosetting polymers by reaction with xylylene glycol and telomers thereof. The prepolymers have been used successfully as molding materials and laminating resins. Glass fiber‐reinforced laminates have been made with flexural strengths of 63 × 10<jats:sup>3</jats:sup> psi and flexural moduli of 4–5 × 10<jats:sup>6</jats:sup> psi. Ferrocene–xylylene glycol copolymers were also prepared, and 1,1′‐bis(hydroxymethyl)ferrocene was used as a polyferrocenylene crosslinking agent. Laminates were also made from the 1,1′‐bis(hydroxymethyl)ferrocene‐based polymers.</jats:p>
