【摘要】 本文合成了具有良好性能的浇铸型不饱和聚酯树脂，对其性能作了进一步研究，结果表明在树脂分子结构一定的条件下，树脂的固化收缩率受单体使用量及填料使用量的影响较大，而固化速度及固化放热主要受固化体系的控制。更多还原

【Abstract】 This paper refers to the compounding of casting unsaturated polyester resin with good property.Through the further study on its`t property,the result is available that with the certain molecule structure of resin,its cure shrinkage varies with the mass of monomer and additive usage,meanwhile the cure speed and exotherm mainly depending on the cure system.更多还原
