The miscibility of tetramethylbisphenol-A polycarbonate (TMPC) with poly(styrene-cotetrahydrofurfuryl methacrylate) (STHFMA) and with poly(p-methylstyrene-co-tetrahydrofurfuryl methacrylate) (MSTHFMA) was studied. TMPC is miscible with STHFMA having THFMA content less than 50 mol% and with MSTHFMA h
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
