Question

small molecules join together by which bond in polyester ​

Answer 1

Explanation:

we will study chemistry and there will atoms & molecules

Answer 2

In this process, when each monomer is added to the chain, an additional, small molecule—such as water—is created as a by-product. Nylon and polyester are made this way.) Addition polymerisation relies on a monomer with a double bond connecting two carbon atoms.
