Preparation of a low polydisperse polymer |
摘要 |
A liquid hydrocarbon soluble difunctional organolithium initiator (DFI) is reacted with an anionically polymerizable monomer, such as isoprene or 1,3-butadiene, in the presence of a diamine or a triamine to form a polymer having low polydispersity and high tensile strength. The DFI is prepared by reacting a dialkenylarylene compound with an alkyllithium in a nonpolar solvent and in the presence of sufficient quantities of a trisubstituted amine to prevent precipitation of the DFI in the solvent.
