    • The scattering prolile in absolute intcnsily units is fit to a Gaussian functional form to determine the full-width at half-maximum (FWHM) and intensity of the primary scattering peak. The functional form used is Iabs, Iincoh+ A* exp, q-qpeak/2σ)2; where Iincoh is the incoherent scattering intensity. A is the intensity prefactor, Iabs, qpeak and σ are the reported absolute intensity, peak position, and FWHM values, respectively
    • peak and σ are the reported absolute intensity, peak position, and FWHM values, respectively.

    • PA A is known to form cyclic polyanhydrides when heated to 150°C due to crosslinking. But crosslinking the disordered block copolymer melts to below the gel point stabilizes the ordered morphology as shown recently by Balsara and coworkers. E. D. Gomez, J. Das, A. K. Chakraborty. J.

    • X-ray reflectivity measurements on blend thin films show that (i) the PAA/P123 blends undergo a cylindrical-to-lamellae transition between 26.5 to 28.5% PAA by mass, and (ii) PAA/P105 blends undergo a lamellae-to-cylindrical transition when PAMPS instead of PAA is added at 20% by mass. The observed order-order transitions are driven more by an increase in the effective interaction parameter, Χ(homopolymer/EO-)-PO, than from a simple increase in the effective chain length, Nhomopolymer + EO.
