The content of 1,2-links in the butadiene fragment of butadine-nitrile rubbers was calculated, the temperatures of the glass transition of rubbers and rubbers based on them were determined. Using the Pearson correlation, it is shown that the mobility of macromolecules of butadiene-nitrile rubbers is de-termined not only by the content of bound acrylоnitrile, but also by the microstructure of the butadiene link. It was found that with an increase in the content of bound acrylonitrile, the change in glass transition tem-peratures between rubber and rubber based on it decreases as a result of vulcanization.
