文摘
- •
OLLA or ODLA segments were grafted on poly(vinyl alcohol) to prepare graft copolymers with variable degree of substitution.
- •
Racemic mixture of PVA-g-OLLA and PVA-g-ODLA in DMSO lead to instantaneous and spontaneous stereocomplex formation.
- •
Further spin-assisted deposition on a surface lead to a thin film that can not be obtained with one homochiral partner only.
