The experimental results show that the influence of temperature on morphology of cured sample is small for poly(vinyl acetate) based LPAs but large for polystyrene based LPA. Polar polymers tend to phase out from UPR and make system form co--continuous structure, which make for shrinkage compensation. Big difference of glass transition temperature $T_{\rm g}$ between UPR and LPA and a $T_{\rm g}$ below the cure temperature are preferred, which make microvoid formation of cured sample have more time and higher efficiency. For the sample with poly(vinyl acetate) based LPAs, the morphology exists two transitions with increasing the LPA concentration. LPA with higher molecular weights needs lower concentration to obtain co--continuous structure. However, for the sample with polystyrene based LPA, the morphology has little change with increasing the LPA concentration.
