The invention relates to compounds represented by the following general formula (1):
1
wherein A is an aromatic compound which may be substituted, or the like, B is a nitrogen atom or CH, X is a lower alkylene group which may be substituted, or the like, Yi s a single bond or the like; Z is a divalent residue of benzene which may be substituted, or the like, and m and n are independently an integer of 1 to 4, and medicines comprising such a compound. These compounds have an excellent inhibitory effect on the production of an IgE antibody and are hence useful as antiallergic agents and the like.

The present invention relates to a process for preparing a branched elastomeric polymer by polymerization of a conjugated diene in the presence of a specific branching agent and a specific stabilizing compound. The branched elastomeric polymer exhibits improved storage stability, as reflected by a constant, or less variable, polymer viscosity over time and with reduced temperature dependence.
