Conducting polymers and applications

The miscibility of poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) with various copolymers of styrene with 2,2,6,6-tetramethylpiperidinyl methacrylate (S-TPMA) was studied by differential scanning calorimetry. While polystyrene (PS) is miscible with PPO at all compositions, S-TPMA copolymer with low TPMA content is miscible with PPO only when the weight percentage of PPO in the blend is 40%. S-TPMA copolymer containing 36% of TPMA is immiscible with PPO at all compositions.
