When monomers combine to form a condensation polymer, another product is also formed. typically, this product is methanol ethene carbon dioxide water?

water

Explanation:

Polymerization is a process in which a large number of small molecules called monomers combine to form a macromolecule called a polymer.

One of the methods employed to synthesize polymers is via condensation reaction. Here, when monomers combine, they release small molecules like water as a byproduct.

For example, condensation reaction between monomers containing a diol group and others containing dicarboxylic acid results in the formation of polyesters along with the elimination of molecules of water per repeat unit as shown below:

n(H2N-X-NH2) + n(HOOC-Y-COOH) →[HN-X-NHCO-Y-CO]n + 2nH2O

for points guys

if you're asking what comes out, it's steam.
