| Abstract: |
| A molecular dynamics method was used to construct a model of hydrogenated nitrile butadiene rubber（HNBR） to study the effect of acrylonitrile（ACN） mass fraction on the thermal properties of HNBR.The results showed that as ACN mass fraction increased，the orientation of HNBR molecular chains of HNBR decreased，the thermal conductivity was reduced，the glass transition temperature rose，and the low-temperature resistance decreased.The non-bonding energy and dihedral angle torsional energy of the molecule had important effects on the glass transition process of HNBR. |
