摘要：
By using the carbon-13 NMR technique, it is shown that there are no cis-1,4-trans-1,4 linkages in an n-BuLi-catalyzed polybutadiene. The polymer consists of ″blocks″ of cis-1,4 units and trans-1,4 units separated by isolated vinyl units. Preliminary evidence suggests this might also be true for other types of 1,3-diene polymerization. Some of the implications of this finding on the mechanism of polymerization are discussed. Tacticity triad distributions are readily determined in polybutadienes with high 1,2 addition contents.
