An organic polymer, having a number-average molecular weight of 800 to 15,000, and comprising 0.5 or more but less than 1. 2 reactive silicon groups in each molecule of the polymer on average, in which the reactive silicon groups are introduced into one-side out of terminals thereof, and heightening, in particular, the proportion of molecules (of the polymer) into each of which the silicon group is introduced. |
