Characteristics and Nomenclature of Copolymers

3.1K
Copolymers are the products obtained from the polymerization of multiple monomer species. So, in a polymer chain itself, there can be multiple repeating units that come from different monomers. The process of synthesizing a polymer from different monomer species is called copolymerization. When two monomers are involved, the polymer is known as a bipolymer. Polymers with three and four monomers are termed terpolymers and quaterpolymers, respectively. Figure 1 depicts the copolymerization of...

Characteristics and Nomenclature of Homopolymers

3.7K
Polymers that are made up of identical monomer units are called homopolymers. Only one repeating unit is involved in the construction of the homopolymer structure. For example, as depicted in Figure 1, polypropylene is a homopolymer constituted of propylene monomers. Here, the only repeating unit in the polymer chain is propylene.

Anionic Chain-Growth Polymerization: Overview

2.4K
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,...

Plasticizers01:31

Plasticizers

235
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Cationic Chain-Growth Polymerization: Mechanism00:57

Cationic Chain-Growth Polymerization: Mechanism

2.7K
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...

Area of Science:

  • Materials Science
  • Civil Engineering
  • Sustainable Construction

Background:

  • Geopolymer coatings (GPC) are explored for surface protection of civil structures.
  • Mixtures utilize a quadruple precursor: fly ash (FA), ground granulated blast-furnace slag (GBFS), metakaolin (MK), and Portland cement (OPC).

Purpose of the Study:

  • To experimentally investigate GPC for surface protection of civil structures.
  • To evaluate setting time, compressive strength, adhesive strength, and permeability.
  • To optimize GPC mixtures for practical applications.

Main Methods:

  • Prepared 85 GPC mixture formulations with varying precursor ratios.
  • Tested setting time, compressive strength (≥35 MPa), and adhesive strength (1.5–3.4 MPa).
  • Assessed permeability using an induced charge passed test, showing a 30% reduction for coated specimens.

Main Results:

  • A preferred GPC formulation was selected based on favorable setting time (≥120 min) and compressive strength.
  • Balancing strength and setting time is achievable through multi-componential precursors and molar ratio-based design.
  • Setting time correlates positively with the molar ratio η[Si/(Na+Al)], with an abrupt increase above 1.1.
  • Compressive strength is enhanced by GBFS, MK, and OPC content, but reduced by FA content.
  • GPC exhibited negligible strength impairment after sustained seawater immersion.

Conclusions:

  • Optimized GPC mixtures provide effective surface protection for civil structures.
  • GPC demonstrates potential for dual benefits: meeting usage requirements and promoting environmental sustainability.
  • The study highlights the viability of multi-component precursors in geopolymer technology for enhanced performance.
