The phase structure of blends consisting of polyvinyl chloride
(PVC) and methyl methacrylate–butadiene–styrene graft copolymer (MBS) are
examined by small-angle-X-ray scattering (SAXS). The interface layer thickness (),
correlation distance (ac), and interface layer specific surface area (Ssp) are
calculated using Debye–Bueche’s statistical theory. The results show that
the grafted sequence of styrene or methyl methacrylate to butadiene–styrene
copolymer have significant influence on the values of , ac, and Ssp. The -value
of PVC/MBS in which styrene is first grafted in MBS is about 5nm larger than
that of methyl methacrylate (MMA) that is first grafted in MBS.
