Reaction mechanism of cationic micellar catalysis upon the hydrolysis of mono-p-methoxy phenyl
The contribution of C--O--C was positive to the photoelastic birefringence; however, the positive contribution of the phenyl
ring was higher than that of C--O--C, leading to a high positive photoelastic birefringence for PPhMA, because the polarizability anisotropy of the phenyl
ring (reported in Ref.
