Synthesis and properties of cross-linkable macromers from the selective substitution of poly(oxyalkylene)-amines and cyanuric chloride

Reactive macromers, consisting of hydrophilic poly(oxyethylene) and hydrophobic poly(oxypropylene) blocks and alternating chloro-triazine linking groups, were prepared from the tri-functional cyanuric chloride and poly(oxyalkylene)-diamines (POA-amines) in a selective manner. Macromers with multiple reactive chlorides could be structurally tailored by varying the ratios of amine/cyanuric chloride, types of the starting POA-amines and temperature (lower than 30 °C). At an elevated temperature (>140 °C), the macromers could be self-cured or cured with additional amine to form polymer films. The films exhibited high thermal stability, solvent-adsorption, and low surface electronic resistivity. The facile synthesis of cross-linkable macromers provides a new synthetic approach for preparing hydrophilic antistatic films with high electrostatic dissipating (<105 Ω/sq) property.
