摘　　要：通过利用常规的投影仪 ,根据 Flory交联结构溶胀理论 ,测定了几种热固性树脂的交联密度。研究显示 。The crosslink density of several thermoset resin systems was determined using an improved method. This method was based on Flory swelling theory of network structure and supposed that the swelling fraction on each side of the resin film is identical. It just involved in using an overhead projector and a white screen (such as white paper, white wall or white board) to measures the swelling fraction for the thermoset resin film in some solvents, and quantitatively calculated the crosslink density. It shows that this simplified method can quantitatively calculate and compare the crosslink density for these thermoset resin systems with similar structure.
