Star-shaped polystyrenes functionalized with carboxylic acid end-groups were synthesized by means of living anionic polymerization of styrene in THF initiated with a multifunctional initiator prepared by the reaction of 1,3-diisopropenylbenzene and potassium naphthalenide (KNaph) in THF at -30 ℃ followed by termination with CO2. Adhesive properties of resulting polymers were investigated by tensile test under the condition of thermo compression bonding between polystyrene and PET films. The star-shaped polystyrene showed high adhesion with PET as compared to linear polystyrene.
