Abstract:

This paper deals with the synthesis of modifiers consisting of co-polyamide with clay prepared from co-monomers, namely from ε-caprolactam (CL) and nylon salt (NS) from adipic acid + diethylenetriamine (ADETA), and montmorillonite (MMT). We present a procedure for evaluating the modifiers’ properties, such as the amount of low molecular compounds (LMC) and the relative viscosity (ηr = ηs/η0) performed in accordance with principles of the five-level two-factor experimental design. Four selected samples were synthesised and their properties were checked.
