AbstractThe effect of heat treatment in the so‐called phase inversion region was studied using uncured mill blends of various commercial styrene—butadiene copolymer rubbers (styrene content, 23.5 to 48 wt‐; styrene block, 0 to 18 wt‐) with general‐purpose polystyrene resin (blend ratio, 80–40: 20–60, in wt‐). It was found that the effect of heat treatment on the hardening or softening phenomenon of blends is different in the random type from that in the block‐type styrene—butadiene copolymer rubber. A thorough discussion led us to conclude that this difference is caused by the strong interaction between the polystyrene block of the copolymer and the styrene homopolymer of general‐purp
