Attapulgite (AT)/natural rubber (NR)/ styrene-butadiene rubber (SBR) nanocomposites have been prepared after attapulgite was modified by different coupling agent. The treatment of AT caused the adhesion between AT nanorods and the nature rubber/styrene-butadiene rubber was improved, which enhanced the tensile properties of the matrix. The tensile strength of composites attained 15.6 MPa after AT was modified by 3%wt Si-69 coupling with addition of 20 phr.

Abstract The possibility of separating linear and branched polymer molecules by chromatography on silica gel is demonstrated. Removal of microgel from styrene-butadiene rubber, SKMS-30 increases the mechanical strength of its vulcanizates; removal of microgel from natural rubber, conversely, reduces the strength. The existence of an optimum branched-structure concentration which insures a gain in various mechanical properties is postulated.
