Summary
This study introduces a new method for synthesizing vinyl-containing polymers using living/controlled Lewis pair polymerization (LPP). This technique allows for the creation of functional polymers with intact vinyl groups, enabling diverse applications.
Area of Science:
- Polymer Chemistry
- Materials Science
Background:
- Vinyl-containing polymers are versatile but challenging to synthesize using traditional methods due to crosslinking.
- Living polymerization techniques require strict control, often hindering the preservation of vinyl pendant groups.
Purpose of the Study:
- To develop a controlled polymerization method for vinyl-containing polymers.
- To enable the synthesis of well-defined polymers with intact vinyl groups for further functionalization.
Main Methods:
- Utilized living/controlled Lewis pair polymerization (LPP) to polymerize allyl methacrylate.
- Employed thiol-ene click reactions for post-polymerization functionalization.
Main Results:
- Achieved synthesis of soluble poly-(allyl methacrylate) with high molecular weights (up to 1143 kg/mol) and narrow molecular weight distributions (Đ = 1.07-1.32).
- Successfully preserved intact vinyl pendant groups in every repeat unit.
- Synthesized well-defined block or random copolymers and various functionalized polymers (e.g., photo-responsive, self-healing, amphiphilic) with tunable architectures.
Conclusions:
- Living/controlled Lewis pair polymerization (LPP) is an effective strategy for synthesizing vinyl-containing polymers.
- The preserved vinyl groups allow for versatile post-polymerization modification via thiol-ene click chemistry.
- This approach offers promising potential for creating advanced functional materials with tailored properties and architectures.

02:34Polymers
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

00:57Cationic Chain-Growth Polymerization: Mechanism
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the generated carbocation,...
01:03Step-Growth Polymerization: Overview
Step-growth or condensation polymerization is a stepwise reaction of bi or multifunctional monomers to form long-chain polymers. As all the monomers are reactive, most of the monomers are consumed at the early stages of the reaction to form small chains of reactive oligomers, which then combine to form long polymer chains in the late stages. Hence, the reaction has to proceed for a long time to achieve high molecular weight polymers.

01:04Anionic Chain-Growth Polymerization: Mechanism
The mechanism for anionic chain-growth polymerization involves initiation, propagation, and termination steps. In the initiation step, a nucleophilic anion, such as butyl lithium, initiates the polymerization process by attacking the π bond of the vinylic monomer. As a result, a carbanion, stabilized by the electron‐withdrawing group, is generated. The resulting carbanion acts as a Michael donor in the propagation step and attacks the second vinylic monomer, which acts as a Michael acceptor.
