摘要：The thiol group-containing polymer of the present invention is represented by the following general formula: HS-(R-S r ) n -R-SH, wherein R is an organic group including a -O-CH 2 -O- bond and/or a branched alkylene group, n is an integer of from 1 to 200, r is an integer of from 1 to 5, and the average value of r is 1.1 or more and 1.8 or less. A curable composition using the thiol group-containing polymer of the present invention can be used in sealants, adhesives, paints and the like, which require properties such as a low specific gravity, a low viscosity and a low glass transition temperature. Furthermore, since the curable composition of the present invention improves elastic recovery and weather resistance, it can be used in sealants, adhesives, paints and the like, which require elastic recovery and weather resistance.
