Abstract
In the present invention, a polymer having a number average molecular weight (Mn) of from 200 to 40,000 and a glass transition point of from -75.degree. C. to +10.degree. C. which is obtained by the cationic polymerization of a branched alpha-olenin is used as a tackifier (a tacky producer) for a hot melt adhesive or a pressure-sensitive adhesive. An adhesive composition containing the polymer described above as a tackifier has excellent heat resistance, hue, weather resistance, and the like and has such excellent characteristics that its odor is weak.
