SEQUENCE MODELING OF RAFT POLYMERIZATIONS WITH THE METHOD OF MOMENTS

Attempts to model the sequence structure of copolymers consisted of probabilistic functions that were incomplete and inaccurate. A novel technique to track sequence parameters is developed that determines not only copolymer composition, but sequence distribution as well. RAFT polymerizations are simulated with two independent and concurrent models to track MWD, conversion, copolymer composition, and sequence characteristics. Batch polymerizations are simulated with varying reactor conditions as a proof-of-concept to illustrate the power of the sequence model to track the composition of ...

Thermodynamics and Relaxation during Actin Polymerization

Actin is the most abundant cytoskeletal protein, accounting for 20% of the total protein content in all eukaryotic cells, especially muscle cells. Actin polymerizes from the globular state known as G-actin monomer to the filamentous semi-flexible polymer, F-actin. This polymerization is involved in cell motility, cell signaling, and even in regulation of ion transport. Actin polymerization is known to be regulated in vivo by more than 150 actin-binding proteins, but was shown early on to be capable of thermodynamic regulation ...

Comparing Microwave Induced Polymerization to Thermal Induced Polymerization of the Resin Bisphenol A-Glycidyl Methacrylate.

This thesis presents a theoretical and experimental comparison of polymerization induced by microwave energy and polymerization induced by thermal energy of the resin bisphenol A-glycidyl methacrylate used in restorative dentistry. The question of whether microwave interaction with the polymer is microwave heating or some more involved microwave interaction with the material is addressed, as part of a general search for relative advantages and disadvantages of the two methods. Results are that the microwave energy was heating the material and that ...
