Notes:
Unliving chains of aliphatic polyester were transformed into dicationically living poly(THF)-block-polyester-block-poly(THF) chains, and four different telechelic triblock co-oligomers with primary, secondary, tertiary amine, and hydroxyl end-groups were synthesized. A novel approach to the exchange of hydroxyl or carbonyl ends of polyester for amino end-groups is described. The primary amine-terminated telechelic triblock was used to modify an epoxy resin to give a toughened product with high strength.
