By considering the fewer number of repeating monomeric units than polymer i.e. Oligomers. How Oligomers are better than polymeric materials in different applications like mechanofluorochromism, gas sensing, or other stimuli-responsive?
Dear all, these are general information : low solution/melt viscosity, less prone to mechanical degradation, ease of synthesis and processing. My Regards
Hi;
Generally speaking, oligomers are considered to be compounds of low molecular weight constituted by a chain of monomers. In this intermediary range of molecular weights between the monomer and the polymers there are important variations in the overall properties of these compounds. An example of these variations is the thermal properties such as the glass transition temperature (Tg), the melting temperature (Tm) or the crystallization temperature (Tc). It has long been known that the Tg of a dispersed material increases as it transitions from an oligomer to a polymer, and recent advances in synthesis allow this effect to be evaluated for defined oligomeric systems with increased resolution and consideration of sequence. This leads to the tuning of these thermal parameters over a wide temperature window, which has a direct impact on the processability of oligomeric materials. For example, in the areas of additive manufacturing or injection molding which target applications such as biomedical implants or organic electronics.
With my best regards
