Abstract
N,N,N',N'-tetramethyl-1,6-hexadiamine and N,N,N',N'-tetramethyl-1,10-diamine were synthesized via methylation reaction.Based on the reaction between the diamine and the active chlorine on PVC forming quaternary ammonium,the diamines were employed as thermally reversible ionic cross-linking agents for PVC.When PVC-U was suitably crosslinked,its Young's modulus,tensile and yield strengths,and elongation at break were increased.When the crosslinkers were applied to PVC-S,tensile strength and elongation at break increased,simultaneously,and the deformation set decreased.The time of crosslinking possessed an effect on the mechanical properties.
