Properties of novel amine-functionalized solution polymerizated styrene-butadiene rubber

Abstract

A new amine compound was used to prepare initiator, which was used to synthesize functionalized solution polymerized styrene butadiene rubber. Carbon black and white carbon black were used to strengthen them respectively, and their dynamic mechanical properties and physical and mechanical properties were tested. The results showed that the tensile strength, hardness, physical and mechanical properties and dynamic mechanical properties of the modified solution polymerized styrene butadiene rubber changed little compared with the non functionalized solution polymerized styrene butadiene rubber; When using silica reinforced system, the physical and mechanical properties of functionalized solution polymerized styrene butadiene rubber were improved, the loss factor at 60 ℃ was significantly reduced, the rolling resistance was improved, and the crosslinking density of the rubber was increased.
