A strategy to reduce the dependence on petroleum-
based building blocks and the disposal concerns
of solid wastes was proposed by developing a novel polymer
blend from bio-based cellulose acetate butyrate (CAB)
and poly(trimethylene terephthalate) (PTT). The thermodynamic
immiscibility and the thermal behaviors of the polymer
melt blends were investigated. The interfacial
properties were analyzed to provide the theoretical guidance
to improve the compatibility of blends. A reactive
compatibilizer, poly(trimethylene terephthalate)-graft-(maleic
anhydride) (PTT-g-MA) was prepared from melt reaction
and characterized with FTIR. The compatibilizer was
melt blended into the CAB and PTT blends. The effects of
different compatibilizers on the phase morphologies and
mechanical properties of blends were characterized and
the interfacial interactions were studied.
