摘要: Poly(N-vinyl pyrrolidone) was blended with an epoxy resin to give a miscible blend. The thermal stability of DGEBA/PVP blends studied by dynamic thermogravimetry. kinetic parameters the degradation were calculated. results indicated that presence one component influences other. In general, PVP has stabilizing effect on DGEBA, but is destabilized DGEBA. chemical interactions between and DGEBA hand, viscosity medium, other seem be factors governing behavior
