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.

Polybutadiene, production and use thereof

The invention relates to the use of silane-modified polybutadienes in rubber mixtures, in particular for improving the rolling resistance of diene rubber tires. In particular, the invention is directed to silane-modified polybutadienes in rubber mixtures, wherein the polybutadiene comprises the 1,3-butadiene-derived monomer units and wherein the proportion of A in the entirety of the 1,3-butadiene-derived monomer units present in the polybutadiene is from 10 to 60 mol %, and wherein the sum of the proportions of B and C in the entirety of the 1,3-butadiene-derived monomer units present in the polybutadiene is from 40 to 90 mol %.

Improving the rolling resistance of diene rubber tires by means of silane-modified polybutadienes

The present invention relates to an optical clear resin and a method for producing a liquid optical clear photo-curable adhesive.

Acrylate-terminated urethane polybutadienes from low-monomer 1:1 monoadducts from reactive olefinic compounds and diisocyanates and hydroxy-terminated polybutadienes for liquid optically clear adhesives (LOCAs)
