Hydrolysis of polymer will produce?

Polymer will reduce only because hydrolysis doesn't produce but polymer does produce.

Monomers.

Explanation:

The process of hydrolysis, reactions tends to breakdown polymers into monomers when they react with water, this process is easily seen as the opposite of dehydration synthesis which only forms water during polymer synthesizing from monomers. Hydrolysis also breaks bonds and release energy during the course of its reactions.

The formed synthesis here, is described as a molecule that forms the basic unit for polymers, they form the basic structures of proteins. Monomers also tend to bind with other monomers to form cycles of chain molecules through polymerization.
