Random copolymers of poly(methyl methacrylate-d8) (PMMA) and poly(methacrylic acid) (PMAA) were synthesized and blended with polyethylene oxide (PEO), and SANS was used to estimate the strength of interaction between the various polymer pairs. The addition of PMAA greatly reduced the scattering of the blend, giving very favorable mixing. Copolymers of the type PMAA-g-PS, PMAA-r-PS, PMMA-g-PS, and PMMA-r-PS (g = graft, r = random) were used as compatibilizers, for the melt blending of mixtures containing 80% PS and 20% PEO. Random copolymers were less effective than graft copolymers at dispersing the polymers. Both PMMA and PMAA grafts were effective with PMAA being better in some cases.
