Abstract

Macromonomers from oxazoline derivates were synthesized by using in conjunction with ethylenically unsaturated modifier. allyl chloride (AC) is chosen as representative modifier for the synthesis of allyl-terminated macromonomers in the presence of an acid exchanged montmorillonite as catalyst. The macromonomers were characterized by FT-IR, 1H-NMR, 13C-NMR and MALDI-TOF mass spectroscopy. The effects of amount of catalyst, amount of initiator, solvent and temperature on yields and intrinsic viscosity were studied. NMR and IR spectra of macromonomers show characteristic chemical shifts absorptions of the ethylenically unsaturated group of the modifier. The MALDI-TOF spectrum shows that the macromonomers synthesized accordingly are terminated with ethylenically unsaturated group of modifier at one end of the polymer chain and a hydroxyl group at the other end.
