文摘
- •
Triblock LA/TMC copolymers (of both A-B-A and B-A-B type) have been synthesized by sequential copolymerization.
- •
Bulky Al-alkoxide initiator eliminating the segmental exchange side reaction allowed the controlled copolymer synthesis.
- •
The assumed copolymer microstructures have been confirmed by 13C NMR spectroscopy.
- •
Influence of the copolymers microstructure on their thermal properties and morphology was investigated.
