Abstract:
To obtain a hydrophilic macromonomer mixture which is a highly polymerized hydrophilic macromonomer, has few components not bonded to the polymer chain after polymerization, and is less likely to leaching. Provided is a macromonomer mixture containing macromonomer A being a macromonomer having a group obtained by further introducing a polymerizable group into a reactive group derived from a polymerization initiator at an end thereof; and macromonomer B being a macromonomer having a group obtained by further introducing a polymerizable group into a reactive group derived from a chain transfer agent at an end thereof.
