低粘度不饱和聚酯树脂的合成与改性研究

Study on Synthesis and Modification of the UP Resin with Low Viscosity and High Reactivity

对低粘度端羟基不饱和聚酯树脂的配方与合成工艺进行了研究。并通过该树脂与异氰酸酯化学共混 ,得到了一种具有粘度低、活性高、力学强度好。

We had studied the formula and synthesis method o f an hydroxyl terminated UP resin with low viscosity. And through blending this UP resin with TDI.We got a resin system with low viscosity, high reactivity and excellent mechanic strength, also can be moulded under room termperature and t ouch pressure.
