(57) [Summary] [Objective] A silicon-containing reactive polymer having a polymerizable group is produced with good reproducibility, easily and inexpensively using an inexpensive raw material. An organic polymer (b) for forming a main skeleton containing an OH group and / or a COOH group is formed by utilizing an exchange reaction to a hydrolyzable organosiloxane (a) having a plurality of R 3 O groups bonded to Si atoms. ), And OH groups and / Alternatively, a reactive organic compound (c) having a COOH group and a polymerizable unsaturated group or an epoxy group is reacted to produce a silicon-containing reactive polymer having a polymerizable unsaturated group or an epoxy group. |
