sidefunctionalisation

Sidefunctionalisation is a term used in chemistry to describe the process of introducing functional groups to the side chains of a polymer molecule. This is distinct from modifying the polymer backbone itself. Sidefunctionalisation allows for the tailoring of polymer properties, such as solubility, reactivity, and adhesion, by attaching specific chemical moieties to the pendant chains.

The methods employed for sidefunctionalisation can vary widely depending on the nature of the polymer and the desired functional groups. Common techniques include post-polymerization modification, where functional groups are introduced after the polymer chain has been formed, or through the use of functionalized monomers during the polymerization process. For example, a polymer with reactive side chains, such as hydroxyl or amine groups, can undergo reactions like esterification, amidation, or etherification to attach new functionalities. Alternatively, monomers already bearing the desired functional groups can be polymerized to directly yield a functionalized polymer.

The applications of sidefunctionalised polymers are diverse and span multiple fields. In materials science, they are used to create specialty coatings, adhesives, and composites with enhanced performance characteristics. In biotechnology, they can be employed in drug delivery systems, biosensors, and as scaffolds for tissue engineering. The ability to precisely control the placement and type of functional groups on the polymer side chains makes sidefunctionalisation a powerful tool for designing advanced materials with specific applications.
