Rare earth-containing PSBR sheet was prepared by reaction of rare earth aikoxide with guaternary ammonium sait of pyridine modified SBR（PSBR）iatex，and then it was biended with naturai rubber（NR）to produce rare earth-containing composite eiastomer. It is found that mechanicai performance can be improved remarkabiy . Anaiyzed by infrared spectrometry（IR），differentiai scanning caiorimetry（DSC）and cross-iinking densitometry， the reiationship between structure and performance was discussed .
