-
The chain structure of 1,2-polybutadienes prepared with molybdenum catalyst systems has been studied by IR,13C-NMR and Tg method, and the method to regulate the chain structure investigated. It was found that some polar additives, e. g., allyl halides, are able to regulate not only the content of 1,2-units in the polymer, but also its configuration and sequence distribution. Attempt has been made to estimate the sequence length of stereo-isomers of 1,2-units by statistical theory.
