Reactive macromers, consisting of hydrophilic poly (oxyethylene) and hydrophobic poly(oxypropylene) blocks and alternating chlorotriazine 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 degrees C). At an elevated temperature (> 140 degrees 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 (< 10(5) Omega/sq) property.
