采用 FT- IR法研究了增塑同步互穿网络 PU/ PGMA的反应动力学。研究了反应温度、引发体系、引发剂浓度、不同组分比等因素对反应动力学的影响 ,得到 PU和 PGMA反应均为二级动力学反应 ,且 PU与 PGMA的反应由于体系粘度的变化 ,存在着相互作用。 PU反应受 PGMA的快速反应的影响而受到抑制
The FT-IR method was used to study the reaction kinetics of PU / PGMA. The effects of reaction temperature, initiator system, initiator concentration and different composition ratio on the reaction kinetics were studied. The reaction of PU and PGMA was second-order kinetic reaction. The reaction between PU and PGMA due to the change of viscosity, There is interaction. The PU reaction is inhibited by the rapid reaction of PGMA
