Novel Anionic Polymerization of -Caprolactam Towards PA6 Containing Nano Plates Morphology

PA6 was prepared via melt polymerization of ε-caprolactam as monomer with sodium caprolactam(NaCL) as a catalyst and Hexamethylene diisocyanate(HDI) or Toloendiisocyanate(TDI) as activator[1].The degree of polymerization and other properties of the resulting polymer depend on the type, method of preparation, and quality andquantity of the activator and catalyst [2,3]. The improvement in polymerization efficiency is caused by using doublefunctional cyanate(HDI/TDI)[1].The novelty of this investigation is the formation of nano plates during melt polymerization of ε-caprolactam. These nano plates can havedifferent molecular weights in comparison with matrix, thus creating special crystal structure being different from that of matrix [1].
