| Abstract: | The polyethylene glycols terminated by reactive maleic anhydride are synthesized and used as a modifier for the high crosslinking degree unsaturated polyester. The products are characterized by FTIR and 1H NMR spectroscopy. The results indicate that the polyethylene glycols terminated by reactive maleic anhydride participate in the curing reaction of the unsaturated polyester and introduce soft segments into the network.The migration of polyethylene glycol in the cured samples is restricted to the surface. |
