Title:
【発明の名称】ジエン系重合体の製造方法およびゴム組成物
Document Type and Number:
Japanese Patent JP3146506
Kind Code:
B2
Abstract:
There are provided a process for producing a diene polymer having markedly improved tensil strength and wear resistance and further having improved heat build-up, refound resilience, processability and wet skid resistance, as well as a rubber composition containing said diene polymer and having improved tensil strength, wear resistance, etc. Said diene polymer is produced by polymerizing a conjugated diene monomer or a mixture of the conjugated diene monomer and an aromatic vinyl monomer in a hydrocarbon solvent using a composite initiator containing an alkaline earth metal, and reacting active ends of the obtained active diene polymer with (a) a compound represented by the formula M=C=M (wherein M denotes an oxygen atom or a sulfur atom) or (b) N-substituted aminoketone, N-substituted thioaminoketone, N-substituted aminoaldehyde, N-substituted thioaminoaldehyde or a compound having an atomic group in a molecule represented by the formula -C(=M)-N< in a molecule.
