PREPARATION OF OLIGOMERS WITH FUNCTIONAL END GROUPS BY POLYMERIZATION REACTIONS

ABSTRACT The possibilities of preparing oligomers with functional end groups by cationic, anionic and radical polymerization are discussed. Special attention is given to oligomers with two functional end groups (telechelic oligomers). By use of efficient separation techniques, especially GPC, these oligomers can be separated and analyzed. The conclusions that can be drawn from the structure of these oligomers with respect to the elementary processes in polymerization reactions are critically examined.
