Translated title:
Synthesis of Linear and Star Copolymers with High Flory-Huggins χ Interaction Parameter
Summary:
Linear block copolymers were synthesized (P2VP-b-PLLA, PLLA-b-P2VP-b-PLLA, PLLA-b-PDMS-b-PLLA) with different Μw and compositions, as well as star copolymers ((PS)2(PGMA), (PS)3(PGMA)), in order to create nanodomains with different morphologies and dimensions and to study the effect of the macromolecular architecture at the microphase separation. These polymers are termed as “high χ” polymers. Due to high incompatibility, low molar mass polymers allow for the formation of very small sizes structures in microphase-separation, constituting useful materials in the microelectronics industry. The synthesis of the polymers was carried out by anionic polymerization and Ring Opening Polymerization (ROP). Size exclusion chromatography (SEC) and Proton Nuclear Magnetic Resonance (1H-NMR) were used for the molecular characterization of these polymers, while the microdomain morphologies were determined by Small-Angle X-ray Scattering (SAXS).
