Condensation of fluoro-substituted and silyl-substituted monomers provides polymers suitable for use, e.g., as engineering polymers. A monomer composition is condensed in the presence of a basic catalyst. The monomer composition contains a compound of formula F&#x2014;X&#x2014;F and a compound of formula (R)Si&#x2014;Z&#x2014;Si(R), and forms an alternating X&#x2014;Z polymer chain and a silyl fluoride byproduct. X has the formula -A(&#x2014;R-A)n-; each A is SO, C(&#x2550;O), or Het; Ris an organic moiety; n is 0 or 1; Het is an aromatic nitrogen heterocycle; Z has the formula -L-R-L; each L is O, S, or N(R); and each Ris an organic moiety, and Rcomprises H or an organic moiety.
