摘要：
A method of producing a thiol group-containing polymer includes reacting bis(2-chloroethyl) formal with sodium hydrosulfide, wherein the thiol group-containing polymer is represented by general formula: HS—(R—Sr)n—R—SH where R is an organic group including a —C2H4—O—CH2—O—C2H4— structure, 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 lower than 1.8, and wherein the thiol group-containing polymer is a liquid polymer.
