  • Polybutadiene, production and use thereof
    Patent number: 11365270
    Abstract: The invention relates to polybutadiene, which contains the monomer units derived from 1,3-butadiene having a vinyl double bond in a proportion of 25 to 75 mole percent, having a trans-double bond in a proportion of 0 to 10 mole percent and a cis-double bond in a proportion of 25 to 75 mole percent, wherein the totality of the monomer units (A), (B) and (C) is supplemented to 100 mole percent, and which is characterized in that it has a number-average mole mass of 1,000 to 3,000 g/mole. The invention further relates to a method for producing polybutadienes, the use of the polybutadiene according to the invention and compositions containing polybutadiene according to the invention.
