Synthetic Polymers
Polymers that are made up of identical monomer units are called homopolymers. Only one repeating unit is involved in the construction of the…
Copolymers are the products obtained from the polymerization of multiple monomer species. So, in a polymer chain itself, there can be multiple…
For any given polymer, the weight average molecular weight (Mw) is higher than, if not equal to, the number average molecular weight (Mn). The only…
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like…
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a…
Chain-growth or addition polymerization is successive addition reactions of monomers with a polymer chain. In radical chain-growth polymerization,…
The skeletal structure of polymers synthesized via radical polymerization is always branched. For example, the polymerization of ethylene by radical…
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth…
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization…
Ziegler–Natta polymerization is another form of addition or chain‐growth polymerization used for synthesizing linear polymers over…
Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas…
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated…
Superhydrophobic materials, with surfaces possessing permanent or metastable non-wetted states, are of interest for a number of biomedical and…
In this study, an amphiphilic copolymer that includes a core-forming block with phenyl groups was synthesized by living anionic polymerization of…
