Abstract
Gradient copolymers with different incompatibility and gradient steepness were employed to design materials with good damping properties over wide temperature ranges (e.g. 70-100 K). A study was carried out on a styrene/hydroxystyrene system (S/HS) with χ = 6 and an S/butyl acrylate system (S/BA) with χ = 0.087. Gradient steepness was controlled by the addition rate of the second monomer during polymerization. The S/HS system showed very broad damping behavior at moderate gradients, due to severe incompatibility of its components. Meanwhile, the S/BA system demonstrated just slightly broadened damping behavior at moderate gradients, but very broad damping was observed at stronger gradients.
