Ethylene ionomer contains amorphous phase, lamellar crystal, and ionic aggregates of multiplet or cluster which are formed by the Coulombic interaction between ionic groups of ionomer. Here SAXS and ESR studies were carried out to elucidate the higher ordered structure of ionic aggregates. The radius of ionic aggregates(R) and the distance between clusters(d) increased with ionic content. R decreased and d increased with temperature. On the other hand, d of styrene ionomer decreased with temperature. Higher ordered structure of both ionomers was found to be different slightly. Fine struture and molecular motion of ionic aggregates of ethylene ionomer were elucidated by ESR. It was found that glass transition of ionic aggregates occured at about 70゜C for ethylene ionomer.

乙烯离聚体含有无定形相、层状晶体和离子基团之间通过库仑相互作用形成的多簇或簇状离子聚集体。在这里进行了SAXS和ESR研究来阐明离子聚集体的高阶结构。离子聚集半径(R)和簇间距离(d)随离子含量的增加而增大。R随温度的升高而减小，d随温度的升高而增大。另一方面，苯乙烯离聚体的d值随温度的升高而降低。发现两种离聚物的高阶结构略有不同。用ESR研究了乙烯离聚体离子聚集体的精细结构和分子运动。发现乙烯离聚体在70℃左右发生了离子聚集体的玻璃化转变。
