What type of product does polymerisation result in?

Polymerisation is a chemical process whereby small molecules known as monomers join together to form larger, more complex structures called polymers. This process plays a crucial role in the production of various materials used in everyday life, such as plastics and elastomers. The resulting polymer molecules often exhibit properties that make them valuable in a wide range of applications, from packaging to textiles.

In contrast, individual monomers are the building blocks that undergo polymerization, and as such, they do not represent the outcome of the process. Natural fibers, while they are long-chain polymers, originate from natural sources and are not the direct result of polymerization in a synthetic context. Similarly, synthetic monomers are the precursors to polymers, not the products of polymerisation itself.

Therefore, the correct answer highlights that the outcome of polymerisation is indeed polymer molecules, which can possess diverse characteristics depending on the types of monomers involved and the conditions under which polymerisation occurs.
