Summary
This study synthesized porous copolymers using allyl methacrylate and divinylbenzene. High surface areas were achieved with specific crosslinker concentrations, indicating unique network formation for potential specialty polymer applications.
Area of Science:
- Polymer Chemistry
- Materials Science
Background:
- Porous polymers are crucial for various applications, including separation and catalysis.
- Tailoring polymer network structure influences porosity and surface area.
Purpose of the Study:
- To synthesize and characterize porous copolymers of allyl methacrylate and divinylbenzene.
- To investigate the effect of divinylbenzene content on polymer porosity and surface area.
- To explore the potential for chemical modification of the synthesized polymers.
Main Methods:
- Suspension polymerization using allyl methacrylate and divinylbenzene with inert diluents.
- Characterization via elemental analysis, FTIR spectroscopy, and nitrogen adsorption at 77 K.
Main Results:
- Synthesized six porous copolymers with varying divinylbenzene (DVB) content (5-50 wt%).
- Polymers with 20-50 wt% DVB exhibited high specific surface areas (410-480 m²/g).
- A notable decrease in surface area at 5-15 wt% DVB suggests unique network formation involving allyl groups.
Conclusions:
- The study demonstrates a novel method for creating porous polymers with tunable surface areas.
- The presence of residual allyl groups offers opportunities for synthesizing functionalized polymers like ion-exchangers and coordinating resins.

Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

00:53Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)
1.9K
Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

2.1K
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...

01:18π Molecular Orbitals of the Allyl Cation and Anion
4.1K
An allyl group is a three-carbon conjugated system where the sp³-hybridized allylic carbon is bonded to a CH=CH2 group via a single bond. Allyl anions can be obtained by treating propene with a strong base that can deprotonate methyl groups. Allyl cations are formed as intermediates during substitution reactions involving allylic halides. In both cases, the hybridization of the allylic carbon changes from sp3 to sp2, giving rise to a carbon chain with three sp2-hybridized carbons, each with...

2.8K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

7.7K
The conversion of alkenes to macromolecules called polymers is a reaction of high commercial importance. The structure of the polymer is defined by a repeating unit, while the terminal groups are considered insignificant. The average degree of polymerization represents the number of repeating units in the polymer molecule and is denoted by the subscript n.
