## Abstract The acidic hydrolysis of polyacrylonitrile, stabilization and thermal gelation in mixed solvents were sequentially carried out to yield a variety of terpolymer gels made up of 58,5 to 89,4 mol‐% units of acrylonitrile, 10,2 to 39,2 mol‐% acrylamide and 0,4 to 2,3 mol‐% acrylic acid. The
A miscible homopolymer-copolymer pair viz., poly(ethyl methacrylate) (PEMA)-poly(styrene-co-butyl acrylate) (SBA) is reported. The miscibility has been studied using differential scanning calorimetry. While 1 : 1 (w/w) blends with SBA containing 23 and 34 wt % styrene (ST) become miscible only above
