摘要：

A process for the chemical modification of polybutadienes and natural rubber by various metallocene compounds is described. In the experiments reported in this paper several soluble products of up to 43% ferrocene content were obtained. The effect of substrate, metallocene, and reaction conditions on the course and extent of substitution was investigated. The glass transition temperature T//g was found to increase considerably with the degree of substitution, e. g. , cis-polybutadiene substituted with ferrocene (18 mole-%) has a T//g of 30 degree C, as compared with minus 91 degree C for the unsubstituted polymer.
