Abstract
A mixture of polymers (A) and (B), each of the polymers (A) and (B) having a polyoxyalkylene main chain structure and a terminal structure bonded to an end of the main chain structure, is provided. The terminal structures include hydrolyzable silyl groups and further include terminal olefin groups and/or internal olefin groups. The number of the terminal structures per molecule of the polymer (A) is 1.5 or more on average and the number of the terminal structures per molecule of the polymer (B) is 1.2 or less on average. In each of the polymers (A) and (B), the total number of the hydrolyzable silyl, terminal olefin, and internal olefin groups is more than 1.0 on average per terminal structure. In the whole mixture, the percentage of the hydrolyzable silyl groups to the total of the hydrolyzable silyl, terminal olefin, and internal olefin groups is from 40 to 75%.
