Ethylene Acrylic Acid copolymer (Ethylene Acrylic Acid EAA) is a thermoplastic and high adhesion of polymer, as a result of the existence of carboxyl group and the effect of hydrogen bonding, polymer crystallization is suppressed, the main chain of the linear are destroyed, thus improve the transparency of EAA and toughness, reduce the melting point and softening point.When the MI phase at the same time, with the increase of AA content, transparency of EAA, toughness, adhesion, environmental stress cracking resistance will increase;On the contrary, its rigidity, wet steam transmittance, creep resistance, chemical resistance will be better.When the content of AA phase at the same time, with the increase of MI, adhesion of EAA, processability, will be better;On the contrary, the toughness, environmental stress cracking resistance will increase
