This invention relates to a process for the synthesis and purification of hydroxyl-end group functionalized, linear, non-crosslinked polyolefins without pendant chain branched groups, and specifically to hydroxyl-end group functionalized polybutadienes. The process comprises polymerizing a cyclic olefin monomer with a chain transfer agent in the presence of a suitable catalyst, thereby forming a protected end-group functionalized polyolefin, followed by adding a mixture comprising water and caustic to the protected end-group functionalized polyolefin to remove the protecting groups, thus forming a hydroxyl end-group functionalized, linear, non-crosslinked polyolefin without pendant chain branched groups.
