Blends of organosilicon polymers with polystyrene, PS, and poly(2,6-dimethyl-1,4-phenylene oxide), PPE, were investigated by transmission electron microscopy and differencial scanning calorimetry. Blends with poly(tetramethylsilphenylenesiloxane), PTMPS, showed a morphology characterized by globular

## Abstract Blends of styrene–butadiene–styrene (SBS) or styrene–ethylene/1‐butene–styrene (SEBS) triblock copolymers with a commercial mixture of polystyrene (PS) and poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) were prepared in the melt at different temperatures according to the chemical kind of
The methyl groups of poly(2,6-dimethyl-l,4-phenylene oxide) (PPO) were brominated to various extents. Bromobenzylated PPO (BrPPO) samples with degrees of bromination of 16, 37, 50, 69 and 76% were found to be miscible with polystyrene (PS) but BrPPO with a degree of bomination of 92% was immiscible
