摘要：
Oligomerizaton of isoprene on initiation by hydrogen peroxide in solutions of methyl, ethyl, propyl and carbon-labelled isopropyl alcohols is studied. The radioactive label method reveals that the functionality of the oligomers for fragments of isopropyl alcohol is about 0 multiplied by (times) 5 irrespective of the molecular weight of the oligomers and degree of monomer conversion. The presence of fragments of isopropyl alcohol with the terminal tertiary OH groups in the oligomer molecule is the cause of the reduced (below 2) 'effective' functionality of the oligoisoprenenes obtained in solution in isopropyl alcohol. In solutions in primary alcohols oligomers containing up to 90% of molecules bifunctional in hydroxyl groups are obtained.
