Abstract

The surface compositions of multiblock copolymers of Bisphenol A polycarbonate (BPAC) and poly(dimethylsiloxane) (PDMS) were studied by angle-dependent X-ray photoelectron spectroscopy. Structure and annealing effects on the PDMS surface concentrations of the BPAC-PDMS block copolymers measured at different ESCA sampling depths (up to 103 Å) are discussed. The glass transition temperatures of the block copolymers and BP AC homopolymer were measured by DSC to determine the annealing temperature for the block copolymers.
