Polymer-type dehydrocondensing reagents comprising of a triazine dehydrocondensing reagent, itself in a polymerized form (Poly-Trz—MMs'), have been developed by exploiting the chemical properties of cyanuric chloride that readily binds to alcohol or amines. A chlorotriazine polymer bearing two alkoxy substituents at the 4-and 6-positions (Poly-O-Trz– Cl) was prepared by alternating copolymerization between cyanuric chloride and tetra ( ...
