- Abstract:
- Thermal, mechanical, and surface properties of a library of poly(2-oxazoline)s are investigated.
These polymers are suitable to study structure/property relationships as their
cationic ROP and the relative facile monomer synthesis allow for control over the
molecular structure. The number of carbon atoms in
the linear side-chain is systematically varied from
methyl to nonyl. Relations between chemical structures,
thermal transitions, surface energies, and elastic
moduli are discussed. It is shown that the mechanical
and thermal properties of the polymers depend on the
presence of a crystalline phase in the material. The
amorphous polymers reveal a decrease in the reduced
moduli along with a decrease in their respective glass
transition temperature with increasing length of the
side-chain.
