Abstract(s)
Inverse gas chromatography was used to study the surface Lewis acid–base properties of the major components of
pigmented, impact-modified, polycarbonate–poly(butylene terephthalate) blends. An investigation of the Lewis acid–base
interactions in these polymeric systems has been carried out, based on the values determined for the surface Lewis acidity
constant (K ), surface Lewis basicity constant (K ) and on the chemical and physical structure of the materials involved. This a b
analysis provided the rationale for an interpretation of the phase separation and the phase preference that exist in these
polymer blends, and of the consequences to their physical and mechanical properties.
