Step-growth polymers

Definition

Step-growth polymers are polymers formed by the reaction of bifunctional or multifunctional monomers, where bonds form between functional groups in a stepwise fashion, leading to high molecular weight polymers. This process contrasts with chain-growth polymerization by involving all monomers at once rather than adding monomers one at a time.

Carboxylic Acid Derivatives:

These are compounds derived from carboxylic acids where the hydroxyl group is replaced by another atom or group of atoms, acting as key monomers in forming polyamides and polyesters through nucleophilic acyl substitution reactions.

Nucleophilic Acyl Substitution Reactions: A chemical reaction where a nucleophile displaces a leaving group attached to an acyl group, commonly involved in creating synthetic polymers including step-growth polymers like polyamides and polyesters.

Polyamides:

A type of polymer formed from the reaction between diamines and dicarboxylic acids or their derivatives through step-growth polymerization, known for their strength and resistance to wear used in materials like nylon
