摘要：

The above-mentioned chemical modification has been developed by slightly modifying the chain-ends using a lithium catalyst system without changing the main chain structure. The chemical modification involves an addition reaction of some polar compounds such as EAB left bracket 4,4 prime -bis-(diethyl amino)benzophenone right bracket . The chemical modification has been applied to both high-vinyl polybutadiene (Nipol BR 1245) and solution-polymerized SBR (Nipol SBR NS 110's). Characteristics of the modified rubbers as compared with unmodified rubbers are the improved rebound resilience (hence low rolling resistance) without sacrificing wet-skid resistance. The purpose of this paper is to clarify the mechanism of the improvement by the chemical modification.
