Abstract Details

2019, Master of Science, University of Akron, Polymer Science.
In traditional elastomeric systems, altering physical properties of the polymer requires changing the crystallinity or monomeric composition. Using organocatalyzed stereospecific additions of thiols to propiolates, physical properties such as elastic modulus, tensile toughness, and ultimate tensile strain can be controllably varied over an order of magnitude. These materials allow for controlled variations in material properties while maintaining monomer composition and stoichiometry. These polymers can be further functionalized via doping with functional monomers. Colorimetric functionality is of specific interest for the application of tamper-evident technologies. These functionalities generate a response capable of being qualitatively identified without the use of instrumentation for ease of instant recognition of mechanical manipulation of the polymer film. Elastomers are excellent candidates for this application due to their low hysteresis over multiple low strain interactions allowing for the breadth of mechanical properties to find use in a variety of applications. This system is also tolerant of enhanced functionality with a variety of functionalized monomers and post polymerization modification strategies.
