MACROMONOMER MIXTURE, TERMINAL-REACTIVE POLYMER MIXTURE, INTERMEDIATE FOR MACROMONOMER AND SILICONE HYDROGEL

摘要

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.

1. A macromonomer mixture comprising macromonomer A selected from Formula e4, e5 and e6: wherein RH is H or methyl; R1 through R4 are groups derived from polymerization of polymerizable monomer expressed by formula (m) 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.
