The adsorptions of polyethylene glycol monomethyl ether (PEGMME) and dimethyl (PEGDME) on CaA, NaX, NaY, ZSM-5 zeolites have been analyzed by using experimental FT-IR Raman spectroscopies. vibration wavenumbers polymers adsorbed reported the adsorption properties with different molecular sizes cations compared. Disappearing some modes or shifts to higher lower frequency region after zeolites; i...
