Abstract
This Master Thesis aims to investigate the effects of various compatibilizers on the
Rheological, Mechanical and Morphology properties of polypropylene (PP) and polystyrene
(PS) blends. PP and PS are immiscible polymers, resulting in poor interfacial adhesion
between them, which leads to inferior mechanical properties of the resulting blends. To
improve the compatibility between PP and PS, different compatibilizers, including maleic
anhydride grafted PP (PP-g-MAH) and styrene-maleic anhydride copolymer (SMA), were
used.
The effect of different compatibilizers on the morphology and mechanical properties of the
PP/PS blends was investigated. The results showed that the addition of compatibilizers
improved the interfacial adhesion between PP and PS, resulting in enhanced mechanical
properties of the blends. Furthermore, the morphology of the blends was also improved, as
evidenced by the reduction in the size of minor phase dispersed in the major matrix.
The findings of this research can have potential applications in various industries, including
packaging, automotive, and construction, where PP/PS blends are commonly used.
