crystallization behavior of pa6 in abs/pa6 blends prepared by in situ polymerization and compatibilization method
a new method was used to prepare abs/pa6 blends by in situ polymerization and compatibilization method. in this process, ε-caprolactam monomer was polymerized in presence of abs via activated anionic polymerization to produce pa6. the main ingredients of the reaction mixture included: monomer ()ε-caprolactam), catalyst na-caprolactamate), microactivator hdi)( and macro-activator sma)(. then, in...
متن کاملPreparation and Characterization of Layered Silicate Polyethylene Terephthalate Nanocomposite by in Situ Polymerization
A series of experiments on the synthesis of poly (ethylene terephthalate) (PET)/organo-montmorillonite (MMT) nanocomposites were carried out in a pressurized reactor using alkyl ammonium exchanged smectite clays, (Closite 30B).Given the degradation of organoclay at high temperatures, the in situ polymerization process was carried out at mild temperatures ranging from 210 to 230°C for 40 minutes...
متن کاملSynthesis, Characterization, and Ring Opening Polymerization of Poly(1,4-cyclohexylenedimethylene terephthalate) Cyclic Oligomers
Cyclic oligomers of poly(1,4-cyclohexylenedimethylene terephthalate) (PCT) were prepared by reaction of 1,4-cyclohexanedimethanol (CHDM) with terephthaloyl chloride under diluted conditions and separated from the linear products by silica gel column at a yield of 23.7 wt %. Cyclic dimer, trimer, tetramer, pentamer, and hexamer were further separated by high performance liquid chromatography, an...
متن کاملRadar absorption of FeNi nanoparticles and FeNi@PANI nanocomposites prepared by in-situ polymerization
In this research, FeNi@PANI nanocomposites as the electromagnetic wave absorbers were prepared through two following steps. At first, FeNi alloy nanoparticles were synthesized by the one-pot polyol process, and then, in-situ polymerization method was used for the preparation of FeNi@PANI nanocomposite. The XRD pattern confirmed the formation of pure FeNi alloy with the FCC crystalline phase. Th...
متن کاملCyclic Oligomers in the Cationic Polymerization of Heterocycles
The cationic polymerization of heterocyclic monomers may lead to polymers containing substantial, yet Variable amounts of cyclic oligomers. This review gives a survey of the systems where such oligomers have been found. Oligomer formation is generally observed in the polymerization of oxiranes and thiiranes. The most frequently observed oligomers are the cyclic dimers and cyclic tetramers but o...
