Fructose-Based Acrylic Copolymers by Emulsion Polymerization

Area of Science:

• Polymer Chemistry
• Green Chemistry
• Materials Science

Background:

• Growing demand for sustainable alternatives to petrochemical-based monomers in polymer formulations.
• Need for high-performance waterborne copolymers for adhesive and coating applications.
• Exploration of renewable resources like low molar mass sugars for monomer synthesis.

Purpose of the Study:

• To synthesize and characterize a fructose-based monomer (MF) for waterborne copolymer applications.
• To evaluate the polymerization behavior and properties of MF-based polymers.
• To investigate the potential of MF as a sustainable replacement for methyl methacrylate in acrylic formulations.

Main Methods:

• Synthesis of a fructose-based monomer (MF) with a methacrylate group.
• Emulsion homopolymerization of MF.
• Characterization of polymer properties including glass transition temperature (Tg) using differential scanning calorimeter (DSC).
• Investigation of polymerization kinetics and particle size evolution.
• Assessment of copolymer formulations and storage stability.

Main Results:

• Successful synthesis of MF and its ability to homopolymerize in emulsion.
• High Tg (approx. 115 °C) of the resulting polymer, suitable for hard material applications.
• MF demonstrated comparable polymerization kinetics and particle size evolution to conventional methacrylates.
• Homogeneous incorporation of sugar units confirmed by a single Tg.
• Increased formulation solids content to 45 wt % and enhanced polymer insolubility over time due to hydrogen bonding.

Conclusions:

• Fructose-based monomer (MF) is a viable renewable alternative for waterborne copolymers.
• MF-based polymers exhibit desirable properties for adhesives and coatings.
• MF's unique post-polymerization behavior suggests opportunities for functionalization and improved adhesion.
