SUMMARY

Thanks to the structure properties, liquid natura! rubber (LNR) was used by several authors

as compatibili:er for polvrner blends based on lite natural rubber This paper gave an orervicw about the influence of the componbilizer TIl I LNR with the end Ol-i-groups 0/1 the morphology and properties of the research blend systems The research results showed that TH J with the molecular weight of 8.500 had the best compatible effect jar the blends NRIP!-.· NRISBR and NRiNBR This cornpatibilizer I'HI was good for the blends the components of which had the tittle polarity difference like NRISBR The phase morphology showed a good component dispersion The mechanical and technical properties of the polymer blends were significantly improved by /Ising this companbili:rr.
