Macromolecular chemistry profoundly shaped the twentieth century through the remarkable development of new materialsi. The ongoing expansion of polymer science is driven by the constant demand for novel materials with unique properties that can enable nnovation.

Macromolecules, polymers, and block copolymers synthesized through living polymerization are particularly well-suited to meet this challenge due to their specific synthesis methods. Poly(vinyl ethers), which can only be polymerized via cationic methods, are known for their adhesive properties and high reactivity. When copolymerized with various vinyl monomers, different types of copolymers can be obtained, which can lead to improved properties.

Maghnite-H+, a true green ecocatalyst, has been the subject of numerous studies and applications involving various vinyl and heterocyclic monomers, including vinyl ethers. The primary objective of this work is to prepare block copolymers based on n-butyl vinyl ether using Maghnite-H+ as the ecocatalyst.

The first step of this study is the synthesis of poly(n-butyl vinyl ether) catalyzed by Maghnite-H+. The resulting polymer will be fully characterized using various analytical methods, including nuclear magnetic resonance (1H NMR), infrared (IR) spectroscopy, gel permeation chromatography (GPC), viscometry, and differential scanning calorimetry (DSC).

The poly(n-butyl vinyl ether) obtained will then be used as a macrocatalyst for the cationic polymerization of styrene (in both bulk and solution). This process aims to produce a PnBVE-b-PS block copolymer. The final product will be characterized using the previously mentioned methods, in addition to thermogravimetric analysis (TGA).
