PURPOSE:To obtain a polymer having narrow molecular weight distribution and useful for paint, using a wide variety of monomers as raw material and minimizing the lowering of the introduction rate of functional group to polymer chain terminal, by carrying out anionic polymerization of an anionic polymerizable monomer in the presence of a specific anionic polymerization initiator. CONSTITUTION:A telechelic polymer having a number-average molecular weight of preferably 500-10,000,000 is produced by carrying out anionic polymerization of one or more anionic polymerizable monomers [e.g. styrene and (meth) acrylonitrile] in the presence of a novel anionic polymerization initiator of formula (R1, R2 and R4-R7 are 1-10C alkylene; R7 may be H; R3 is 1-10C alkylene; M is group Ia metal element) [e.g. o-, m- or p-(2-trimethylsiloxyethyl) cumene potassium or cesium compound] and, if necessary, reacting the resultant polymer with reagent capable of introducing a functional group with a crosslinking group at a growing terminal of polymer.
