    Area of Science:

    • Polymer Chemistry
    • Materials Science

    Background:

    • Tertiary aromatic amines are crucial accelerators in composite polymerization.
    • Optimizing composite properties requires careful selection of accelerators.

    Purpose of the Study:

    • To evaluate newly synthesized tertiary aromatic amines as curing agents for composites.
    • To compare their performance against commonly used accelerators.

    Main Methods:

    • Composite materials were cured using novel tertiary aromatic amines.
    • Mechanical properties (compressive and tensile strength) were measured.

    Main Results:

    • Composites cured with new amines exhibited favorable overall characteristics.
    • Maximum strength was achieved within a narrow concentration range of the accelerator.
