PROBLEM TO BE SOLVED: To provide a dynamically crosslinked product capable of improving processability by lowering melt viscosity while maintaining low air permeability.SOLUTION: The dynamically crosslinked product according to an embodiment contains a nylon resin forming a continuous phase, a crosslinked product of a rubber dispersed in the continuous phase, and a fatty acid amide lubricant. A low air-permeable film according to one embodiment comprises the dynamically crosslinked product. A pneumatic tire according to one embodiment includes the low air-permeable film. A method for producing a dynamically crosslinked product according to one embodiment comprises: kneading a nylon resin and a rubber together with a crosslinking agent to dynamically crosslink the rubber; and adding a fatty acid amide lubricant and mixing them after the crosslinking.SELECTED DRAWING: None

    【課題】低空気透過性を維持しつつ、溶融粘度を下げて加工性を改善することができる動的架橋物を提供する。【解決手段】実施形態に係る動的架橋物は、連続相をなすナイロン樹脂と、前記連続相中に分散したゴムの架橋物と、脂肪酸アミド系滑剤と、を含むものである。一実施形態に係る低空気透過性フィルムは、該動的架橋物からなるものである。また、一実施形態に係る空気入りタイヤは、該低空気透過性フィルムを備えたものである。一実施形態に係る動的架橋物の製造方法は、ナイロン樹脂とゴムを架橋剤とともに混練してゴムを動的に架橋し、架橋後に脂肪酸アミド系滑剤を添加し混合するものである。【選択図】なし
