1,3-Butadiene is an organic compound that is a simple conjugated diene hydrocarbon (dienes have two carbon-carbon double bonds). Polybutadiene forms by linking many 1,3-butadiene monomers to make a much longer polymer chain molecule. In terms of the connectivity of the polymer chain, butadiene can polymerize in three different ways, called cis, trans and vinyl. The cis and trans … WebLithene ultra AH is a highly viscous, low molecular weight, liquid polybutadiene with a high content of 1,2 vinyl and cyclic vinyl microstructures. It is a low odour and low VOC product used as a binder in automotive adhesives, coagent for EPDM rubbers and in hard electrical encapsulation systems.
