WebJan 7, 2005 · The efficiency of the diamines 1,12-diaminododecane (C 12 N 2) and (4,4′-methylene)bis(2,6-diethylaniline) (MDEA) used as coupling agents for maleic-anhydride-grafted polyethylene (PEgMA) was compared. The effect of the miscibility of the diamines on the course of the reaction with PEgMA was investigated. Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. This colorless liquid with an ammonia-like odor is a basic amine. It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998.
