**Abstract**
 Modified and non-modified composites of PP and LLDPE filled with magnesium hydroxide were investigated, and maleic acid anhydride-grafted PP or LLDPE were used as polymeric modifiers, (MAH-g-PP, or MAH-g-LLDPE) to enhance the interaction between the flame retardant filler and the polymer. When LLDPE was partially replaced by MAH-g-LLDPE, it was found that the notched Izod impact strength, tensile strength, and flexural strength of the composites increased, while the modulus decreased. When the PP was partially replaced by MAH-g-PP, the tensile strength and flexural strength of the composites increased, and the impact strength and modulus changed slightly. The phase structure of the composites was characterised using SEM, DMTA, and DSC which provided evidence to suggest an encapsulation of LLDPE or PP around magnesium hydroxide filler particles in the PP/LLDPE composites containing MAH-g-LLDPE or MAG-g-PP. 13 refs.
