graft the active radicals of acyl caprolactam using the activity of anhydride and obtain PI modified nylon resin by polymerization.When the system temperature is above 160°C and the added modifiers are greater than 10%, the system viscosity increases very fast; when the system temperature reaches...
The grafting of polyamide 6 (PA6) onto polystyrene (PS) can rely on the use of a copolymer of styrene (St) and 3-isopropenyl--dimethylbenzene isocyanate (TMI), PS-co-TMI, to activate the polymerization of 蔚-caprolactam (CL) in the presence of sodium 蔚-caprolactam (NaCL) as an ...
extrusion was used now with higher production efficiency,simpler production facility,higher macromolecular weight and higher cost performance.Latest studies on anionic polymerization nylon 6 by reactive extrusion were summarized.Development prospect of the nylon6 synthesis by reactive extrusion was also ...
1) anionic polymerization 阴离子法 1. Consequently, a kind of graft polymer of PP and PA was successfully prepared via theanionic polymerizationprocess. 利用PP-g-MAA接枝链上的羧基与2,4-甲苯二异氰酸酯反应的产物进行阴离子接枝聚酰胺(PA)6,阴离子法制备了PP/PA6接枝物。
A temperature of 150掳C was demonstrated to be the most appropriate. It was also found that crystallization may occur during PA6 polymerization and that the combination C1/C20 was well suited as it permitted a suitable induction time. Isoviscosity curves were drawn in order to determine the ...
Du Libo,Yang Guisheng.Synthesis and properties of SMA-g-PA6and PPO blend via in situactive anionic polymerization of ε-caprolactam, Comparing with MCPA6/PPO blends. Journal of Applied Polymer Science . 2008Du Libo,Yang Guisheng.Synthesis and properties of SMA*g-...
There is a strong demand for a kinetic model of viscosity development of polyamide 6 (PA6) in computer-aided engineering applications. In this study, a viscosity model was developed by modifying the Castro-Macosko model to include simultaneous polymerization and crystallization effects. Differential ...
Nylon-6 (PA6) nanocomposites were prepared through in situ ring-opening polymerization of 蔚-caprolactam initiated by lipoic acid functionalized MoS2 (f-MoS2). MoS2/PA6 composites were prepared by melt blending of pristine MoS2 powder ... X Wang,EN Kalali,De-Yi Wang - 《Journal of Materials ...
And then inKevlar fiberAnionic ring opening polymerization of caprolactam monomer was carried out on the surface, and the PA6 oligomers on the fiber surface were similar polymers with the matrix PA6 resin. Therefore, the two have good compatibility and effectively improve the tensile strength, flexur...
