Evaluation of Process Degradation of Polymer Formulations Utilizing High-Throughput Preparation and Analysis Methods

Polymers exhibit complex degradation mechanisms during their processing and end use. High‐throughput development of new polymer formulations requires new methods for material preparation and measurement of properties. We explore various approaches to increase the throughput and decrease the sample size for evaluating the relative effectiveness of process stabilizers for poly(propylene). Our several measurement methods for rank ordering stabilizer effectiveness are attractive for rapid identification of high performance stabilizers. Combinatorial polymer microextrusion system.
