| 摘 要： | 采用熔融共混的方法制备聚乳酸(PLA)/聚甲基丙烯酸甲酯(PMMA)共混物相容性问题.研究结果表明在我们所研究PMMA分子量范围内,无定形DL-PLA与PMMA具有较好的相容性,并符合Gor-don-Taylor公式.当结晶型PLLA与PMMA熔融共混时,PMMA的引入破坏了PLLA的结晶,PLLA与PM-MA也表现出良好的相容性.

| Abstract: | PLA/PMMA blends were prepared by melting blending.The miscibility of amorphous DL-PLA and semi-crystalline poly(Llactide)(PLLA) with PMMA of different Mw were investigated by DSC.The results showed that in the range of the molecular weight of PMMA in our study amorphous DL-PLA and PMMA are miscible systems,which obeyed the Gordon-Taylor equation.When the semi-crystalline poly(Llactide)(PLLA) blended with PMMA,the crystallization of PLLA was greatly restricted by amorphous PMMA and showed good miscibility. |
