Abstract
The dynamic viscoelastic properties of PMR-15 polyimide resin during thermal curing have been studied by the parallel-plate technique. The stoichiometry and molecular weight distribution of the imidized prepolymer are shown to have a strong influence on flow behavior during cure. Hydrolysis of polyamide acid intermediates and preferential reactivity of monomeric ingredients are discussed as factors contributing to the broad molecular weight distribution of the imidized prepolymer. Low molecular weight oligomers were prepared, and their effect on cure rheology studied. The presence of the lowest molecular weight oligomer was found to be critical to PMR-15 flow properties during cure.
