| titleOfInvention | Process for producing block copolymer |
| abstract | 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. |
