Abstract:1,3,5-Triazine-based polymers are well-known for their outstanding
   comprehensive properties including excellent thermal stability,high
   strength and modulus,good flame retardance and chemical
   resistance.However,such polymers always exhibit high melt or infusion
   temperatures together with poor solubility,and high-molecular-weight
   polymers are frequently prepared at high temperature under high
   pressure,which hamper their wide spread utilization as high-performance
   separation membranes,insulting coatings or sealants.By using molecular
   design,new series of soluble and heat-resistant poly(aryl ether)s
   containing 1,3,5-triazine moieties were prepared by the incorporation of
   flexible pendant groups,unsymmetrical units,kink or twisted non-coplanar
   moieties into the polymer chain.The effect of molecular structure on
   polymer solubility,thermal stability and mechanical strength was
   investigated in this paper.
