| Abstract: | A reactive terminated polyethylene-glycol was synt he sized and studied by 1H-NMR. The curing behaviors and kinetics of polyethy lene-glycol-modified unsat urated 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 indica te that polyethylene glycol containing reactive terminated maleic anhydride can participate in the curing reaction of unsaturated polyester, which makes the cur ing temperature decrease and accelerates the curing reaction process. |
