DOI: dx.doi.org/10.14314/polimery.1987.467

Summary

A rapid and simple method for the viscometric determination of the average molecular mass of linear oligodiols with the use of Hbppler viscometer has been worked out. This method has been used in quality control of Poles 50/20 oligoesterdiol and in the calculation of equivalent amounts of diisocyanates to oligoesterdiols in the manufacture of PUR elastomers.
