The modification of engineering thermoplastics using functional maleimide derivatives has attracted increasing attention due to the possibility of tailoring mechanical, thermal, and rheological properties. In this study, a comparative investigation of the dynamic and kinematic viscosity of composite materials based on ortho-, meta-, and para-carboxyphenylmaleimide (o , m-, p-CPhMI) incorporated into acrylonitrile–butadiene–styrene (ABS) was carried out. The positional isomerism of the carboxyl group within the phenyl ring plays a crucial role in intermolecular interactions, compatibility, and chain mobility within polymer blends.
Composite samples containing different ratios of CPhMI isomers in the ABS matrix were prepared by melt blending under controlled processing conditions. The rheological behavior of the obtained materials was evaluated using rotational viscometry to determine dynamic viscosity as a function of shear rate and temperature. Kinematic viscosity values were calculated based on measured density and dynamic viscosity data.
