✦ Synopsis

The role of the interface modifier, m-phenylenedimaleimide (BMI), and a lubricant (a mixture of fatty acid amides and esters) in the reactive processing of poly(propylene)/magnesium hydroxide-based composites has been studied. In this investigation process a three-factorial experimental design has been used as a tool to investigate the simultaneous effect of interface modifier, lubricant and processing temperature, with respect to mechanical properties. All of the latter variables were found to influence the properties of the composites. It was found that the significant improvement in mechanical properties (ca. 100%, relative to unmodified composite) afforded by BMI was not, with correct formulation, offset by the detrimental effect associated with the lubricant. The effect of temperature was complex but appeared to be strongly influenced by the BMI level.
