Gas transport properties in homogeneous blends of PMMA with each of two SAN random copolymers, containing 13.5 and 28% by weight of acrylonitrile respectively, have been measured a t 35OC for He, H,, O,, N,, Ar, CH,, and CO,. For all cases, the permeability and diffusion coefficients are higher than
The phase behaviour of poly(styrene-co-methyl methacrylate) blended either with poly(styrene-co-acrylonitrile) or poly(styrene-co-maleic anhydride) was studied. The blends were found to be miscible in certain ranges of copolymer compositions. Light scattering and DSC measurements showed them to phas
