Abstract: A reactive terminated polyethylene_glycol was synthesized and studied by 1 H_NMR.The curing behaviors and kinetics of olyethylene_glycol_modified unsaturated polyester for Bulk Moulding Compound were investigated by using the techniques of IR and DSC.The curing kinetics parameters of the modified system were obtained by Kissinger equation and Crane equation .Research results indicate that polyethylene glycol containing reactive terminated maleic anhydride can participate in the curing reaction of unsaturated polyester , which makes the curing temperature decrease and accelerates the curing reaction process.

Key words: unsaturated polyester, polyethylene glycol, curing reaction, reaction kinetics
