Surface and Bulk Properties of Polydimethylsiloxane Modified Polyether-ester Polyimides

A series of polydimethlsiloxane (PDMS) modified polyether-ester polyimides based on aminopropyl terminated polydimetthylsiloxane oligomer (ATPS) were prepared by two methods, which were copolycondensation of ATPS with p-aminobenzoate terminated poly (tetr
