Abstract:
1. A bulk polymerization composition for producing acrylic polymers having a secondary alcohol at a terminus of the polymer molecule, said polymerization composition comprising: (a) an acrylic monomer in an inert gas atmosphere substantially in the absence of an active gas, and substantially in the absence of a solvent; and (b) a catalyst having a polymerization initiation ability and having at least one thiol group and a secondary hydroxyl group and represented by formula (I): wherein R 1 to R 5 are each independently a hydrogen atom or an alkyl group of 1 to 12 carbon atoms and R 6 is at least one group selected from the group consisting of a hydroxyl group, an alkoxy group of 1 to 12 carbon atoms and an alkyl group of 1 to 12 carbon atoms.
