The invention concerns fluorofunctional statistical polymers of formula (V1), wherein: X, Y and Z represent a hydrogen atom and exhibiting in particular low glass transition temperatures obtained in particular from a B monomer of formula (I): F2C═CF—RF—SO2F, wherein: RF...
In the case of azopolymers, SRGs can be generated by two main procedures: pulsed or continuous laser irradiation. In this article, we discuss the possibility of obtaining stable SRGs with azopolysiloxanes with low glass-transition temperature values, depending on the illumination type. These ...

The glass transition temperature corresponds to the sudden drop in the shear modulus as a function of the temperature. It can be determined from the graph representing the variations in the torsional modulus as a function of the temperature, these variations being measured by thermomechanical analysis...
They do however have sufficiently low glass transition temperature (BR: Tg around −105 °C, VMQ: Tg around −129 °C) for Martian conditions. While the Tg of BR might be slightly too high, proper dispersion of the VMQ phase in the BR matrix might allow it to function properly in ...
(2) Low glass transition temperature (Tg) The ion conductivity is claimed to correlate with the polymer segment motion64. Thus, a lowTgfacilitating the polymer chain mobility is preferable for the enhancement in ion conductivity at ambient temperature. ...
These polymers were characterised by infrared, viscosity and thermogravimetric analysis. The glass- transition temperature, the tensile strength at break, and elongation were also determined.
