Natural rubber (NR)includes about 3 wt%~7 wt% none rubber components (NRCs). It is the NRCs that have transferred the structure of NR from linear to supramolecular by the means of non-covalent interactions such as hydrogen bonding

ionic bonding. The above unique structure has given irreplaceable properties such as strain induced crystallization

modulus self-recovery after shearing and good adhesion to metal compared with Isoprene Rubber (IR). Because of the above properties

NR has widely used in aviation tires

engineering tires

tank roadwheels

air springs and other extreme service conditions. In this article

we make a systematic and comprehensive summary of this field based on effects of NRCs on relationship between supramolecular structure and performance of NR. The species

content and methods for determining content of NRCs have firstly introduced; three aspects are discussed in more detail: the structure of modified end groups of polymer

the mechanism for supramolecular structure and the relationship between the structure and performance. Meanwhile

the future direction of development is discussed as well.
