Head-to-head polystyrene was studied by NMR relaxation measurements in solution and these measurements were compared with those for head-to-tail polystyrene. By measuring the relaxation of the ortho and meta carbons of the phenyl rings of the polystyrenes, it was found that the head-to-head polystyr
