Methods of Converting PVC to Elastomers
The Problem: PVC is the third most produced plastic globally and is used in many applications, such as clean water, due to its versatility. Nevertheless, the chlorine atoms within PVC, and the presence of additives can make it very difficult to recycle. Current thermomechanical methods of recycling PVC often result in quality degradation that limits...

Synthesis of Linear Polyethyleneimine by Living Anionic Polymerizations
­ The Problem: Polyethyleneimine (PEI) is a unique polymer that has a wide range of commercial and research applications. It is most commonly formed by the cationic ring-opening polymerization (CROP) method, which creates a highly branched polymeric structure. The high degree of branching is the result of secondary amines along an existing PEI...
