Influences of poly[(styrene)x-stat-(chloromethylstyrene)y]s additives on dewetting behaviors of polystyrene thin films: effects of polar group ratio and film thickness

► Efficient method for improving stability of polystyrene (PS) thin films. ► Poly(styrene-stat-chloromethylstyrene)s are used as dewetting inhibitors. ► Thermal stability of blended PS/copolymers greatly improved. ► Effectiveness of the copolymers increases with mole ratio of chloromethylstyrene group. ► Important results for designing materials in coating application.
