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.

摘要： An alternate procedure for preparing multilithium initiators using DVB has been developed in order to achieve better control over the specific number of anionic sites per initiator molecule and to prepare star-block copolymers having a pre-determined number of branches. The process consists of 3 distinct steps; oligomerization, activation and polymer growth. The initial step involves the oligomerization of DVB yielding a mini-block having a predetermined number of pendant vinyl groups using a monofunctional initiator such as polystyryllithium. This is quickly followed by activation of the pendant vinyl groups using s-butyllithium prior to polymer growth.

摘要： An improved method for the polymerization of mixtures of mixed cis and trans-isomers of 1,3-pentadiene in the production of block copolymers. By continuously or incrementally adding a cis-isomer of 1,3-pentadiene polymerization promoter, using a hydrocarbon solvent with no aprotic solvents of a polar nature and not exceeding specified temperature ranges, the cis-isomer of 1,3-pentadiene is polymerized, resulting in a greater 1,3-pentadiene polymerization yield. The polymerization promoter is a vinyl-substituted aromatic monomer, for example styrene.

摘要： A self-curing block copolymer, which has improved elastomeric properties without being subjected to any special chemical or physical treatment, is obtained by a single-stage process which comprises subjecting coexistent conjugated diene and vinylsubstituted aromatic hydrocarbon to the action of a dilithium catalyst, and, after substantial completion of polymerization of the conjugated diene, adding a chelating bi- or tri-functiona Lewis base to continue polymerization of the vinyl substituted aromatic hydrocarbon. The block copolymer thus obtained has a high tensile strength and high elongation in the unvulcanized state and can be processed similarly to a thermoplastic resin by injection and extrusion techniques.
