Abstract:
A process for bulk polymerization comprising polymerizing an acrylic monomer in an inert gas atmosphere substantially in the absence of an active gas, and substantially in the absence of a solvent using thioglycerol having a polymerization initiation ability and having at least one thiol group and a secondary hydroxyl group as a catalyst, wherein the amount of the thiol groups in the thioglycerol is used in an amount of 0.5 to 35 mol based on 100 of the number of moles of the unsaturated groups in the acrylic monomer, wherein the bulk polymerization reaction is carried out at a temperature of 25 to 120Â° C., and substantially without a thermally initiated polymerization reaction, and wherein the product of the bulk polymerization comprises acrylic polymers having a secondary alcohol at a terminus of the polymer molecule.
