【52 RSC Advances】 Flammability properties and electromagnetic interference shielding of PVC/graphene composites containing Fe3O4 Nanoparticles
The effects of combined graphene/Fe3O4 nanoparticles on the flame retardancy and smoke suppression of PVC were studied. The dispersion state of graphene in the PVC matrix was improved with the help of Fe3O4 nanoparticles. As a result, the peak values of heat release rate and smoke production rate measured by cone calorimetry were obviously decreased in the PVC/graphene/Fe3O4 composites. According ...

20. Effect of Entanglement Density on Mechanical Properties and Deformation Behavior of Rubber-Modified PVC/α-MSAN Blends
Miscible blends of poly(vinyl chloride) (PVC)/poly(α-methylstyrene-acrylonitrile) (α-MSAN) were toughened by polybutadiene-g-poly(styrene-co-acrylonitrile)(PB-g-SAN). The PB-g-SAN content was fixed at 20%, and the ratio of PVC to α-MSAN ranged from 100/0 to 0/100 in the matrix. The dependence of mechanical properties and deformation mechanisms on the entanglement dens...

活性硅醇改性PVC膜的研究
以廉价的水玻璃为原料，用酸化法从水玻璃中得到硅的有机化合物——活性硅醇，并将活性硅醇直接掺杂到PVC膜中。实验结果表明：用活性硅醇掺杂，流涎法制得的PVC膜，硅在PVC膜中的分布均匀，粒径在10μm以下；硅改性后的PVC膜耐热性有了较为明显的改善。活性硅醇改性PVC膜经NaOH浓溶液处理溶去其中的SiO2粒子后，形成了具有均匀微小孔洞的膜。其孔径与SiO2粒子的粒径相近。通过控制活性硅醇在PVC膜中的质量分数制备含有不同孔径的PVC...

Synthesis of the complex of lanthanum (III) with N-(2-amino ethyl) maleamic acid radical and its application to PVC as thermal stabilizer
The complex (LaL3) of lanthanum (III) with N-(2-amino ethyl) maleamic acid radical (L) was synthesized and characterized by Fourier infrared spectrum (FT-IR), elemental analysis and melting point measure-ments. The complex LaL3 was a chelate, in which lanthanum (III) ion was coordinated with the carboxylate oxygen and amide nitrogen atoms of N-(2-amino ethyl) maleamic acid radical (L). The sta...
