چکیده

Polymethyl methacrylate (PMMA) is frequently used in architectural and biomedical applications due to its consistency, rigidity, and transparency.
With the use of a polyester binder, this study outlines a novel method for enhancing joint strength in structural acrylic (polymethyl methacrylate, or PMMA) after grafting with Acrylamide. PMMA joints' strength was considerably increased. Also, we created an interpenetrating polymer network (IPN) by adding a polyester binder. However, its mechanical performance is limited by its inherent brittleness. FTIR and NMR tests verified the grafting procedure, while scanning electron microscopy (SEM) showed enhanced morphological uniformity.

Tensile and impact testing showed significant gains in strength and toughness. Tensile experiments were conducted to investigate the mechanical properties of acrylic joints at various temperature settings. A constitutive model was created to correlate the strength of the two base materials. Tensile test findings showed that the unique bulk polymerization technique effectively increased joint material strength by up to 45% of the base material's strength.

This advancement in joint strength augmentation not only broadens the potential applications of acrylic glass in architectural structures, but it also provides a sound theoretical foundation for construction procedures. The polyester binder functioned as a reinforcing matrix, increasing energy dissipation and flexibility. The combination of PMMA-g-AA and polyester presents a potential route to high-performance polymer composites.
