摘要
本文基于Cahn的旋节分离理论,用激光散射技术测定了聚氯乙烯(PVC)/丙烯酸酯类弹性体(L_2ACR)的旋节分离线,用相差显微镜跟踪观察、记录了相分离过程中相态结构的变化,并水平扫描记录了调幅结构的V_v散射图形的强度峰。
The phase separation kinetics for blends PVC and linear poly-(methylmethacrylate-co-butyl acrylate ) (L2 ACR) was investigated according to Cahn' s linearized theory about spinodal decomposition with laser scattering technique and its spinodal line was obtained. Furthermore, the phase structure patterns during phase separation process were tracked, obserced and recorded by phase contrast microscopy and the intensity peak pf Vv scattering pattern charactered by modulated structure was scanned.
