材料および材料混合物の流動特性、Huethig & Wepf,Press Bassel−Heiderberg−New York,1986。
酢酸ビニル含量:>35モル%
MVI:(190℃/2.16kg)>20
グラフト度:0.2〜3%(特に0.5〜1.5%)
ゲル比率:<5%、好ましくは<1%
[O]全体−[O]EVA=[O]グラフトされたMAH
[O]グラフトされたMAHx[(C+H)/O]MAH=[C+H]グラフトされたMAH
MAHグラフト度=[MAH]EVA−g−MAH=[O]グラフトされたMAH+[C+H]グラフトされたMAH
架橋されたEVA相と相溶剤EVA−g−MAHのゲル比率は、クロロホルムを用いた熱抽出によって測定した。更に、サンプルを、沸騰したクロロホルム中で還流しながら15時間抽出した。不溶性部分を分離した後、後者を一定重量となるまで乾燥し、その後、重量測定した。最初の重量に対する不溶性残渣の重量比率は、%でのゲル比率を示している。
実施例3及び4と同様にして、成分グリラミッドL16A、レバメルト500及び、実施例1にて製造した相溶剤EVA−g−MAHから成る動的架橋したPA12−EVA混合物を生成する。油膨潤及び機械的特性は、DIN引張強度試験バール上で測定した。
