Abstract: The present invention relates to a method for producing a reactive silicon group-containing organic polymer having a reactive silicon group represented by the following Formula (1), the method including reacting an unsaturated group-containing organic polymer with a silylating agent in the presence of a group 8 metal catalyst and a co-catalyst containing a carboxylic acid compound having a carbon-carbon double bond at an ?-position carbon, —SiRaX3-a??Formula (1) [in the Formula (1), R is a monovalent organic group having 1 to 20 carbon atoms and represents an organic group other than a hydrolyzable group, and X represents a hydroxyl group, a halogen atom, or a hydrolyzable group; a is an integer from 0 to 2; when a is 2, R groups may be the same as or different from each other, and when a is 0 or 1, X groups may be the same as or different from each other.
