Flory Convention
In polymer science, the Flory convention is a convention for labelling conformational isomerism , rotational isomers of polymers. It is named after nobel prize-winning Paul Flory.Morris PJT (1986). "Polymer Pioneers: A Popular History of the Science and Technology of Large Molecules". Center for History of Chemistry, Philadelphia. The convention states that for a given bond, when the dihedral angle formed between the previous and subsequent bonds projected on the plane normal to the bond is 0 degrees, the state is labelled as "trans", and when the angle is 180 degrees, the angle is labelled as "cis".

Polymer Science
Polymer science or macromolecular science is a subfield of materials science concerned with polymers, primarily synthetic polymers such as plastics and elastomers. The field of polymer science includes researchers in multiple disciplines including chemistry, physics, and engineering. Subdisciplines This science comprises three main sub-disciplines: * Polymer chemistry or macromolecular chemistry is concerned with the chemical synthesis and chemical properties of polymers. * Polymer physics is concerned with the physical properties of polymer materials and engineering applications. Specifically, it seeks to present the mechanical, thermal, electronic and optical properties of polymers with respect to the underlying physics governing a polymer microstructure. Despite originating as an application of statistical physics to chain structures, polymer physics has now evolved into a discipline in its own right. * Polymer characterization is concerned with the analysis of chemical st ...
