ETHYLENE GLYCOL POLYMER MODIFIED WITH METHYLTHIOMETHYL GROUP, METHOD FOR PRODUCING THE SAME AND USE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a compound forming a linker for bonding a soluble polymer carrier consisting of a polyethylene glycol derivative to a compound having OH group. SOLUTION: An ethylene glycol polymer derivative modified with methylthiomethyl group and expressed by the formula: CH3-O-(CH2CH2O)n-CH2-S-CH3[wherein, (n) is 1-900, preferably 110±integer] is obtained by converting the hydroxy terminal of a polyethylene glycol monomethyl ether forming the polymer carrier part into methylthiomethyl ether for supplying the linker part.
