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—X—F and a compound of formula (R
1
)3Si—Z—Si(R
1
)3, and forms an alternating X—Z polymer chain and a silyl fluoride byproduct. X has the formula -A(-R
2
-A)n-; each A is SO
2
, C(═O), or Het; R
2
is an organic moiety; n is 0 or 1; Het is an aromatic nitrogen heterocycle; Z has the formula -L-R
3
-L-; each L is O, S, or N(R

); and each R
3
is an organic moiety, and R
4
comprises H or an organic moiety.
