Polymer thermodynamics
WebThermodynamics is an indispensable tool for developing a large and growing fraction of new polymers and polymer blends. These two volumes show the researcher how thermodynamics can be used to rank polymer pairs in order of immiscibility, including the search for suitable chemical structure of compatibilizers. WebJan 21, 2012 · PSC 480/740 Kinetics. 2. Thermodynamics of Polymerization (continued). Since most polymerizations are characterized by an exothermic propagation reaction and an endothermic depropagation reaction, the activation energy for the depropagation reaction is higher, and its rate increases more with increasing temperature compared to the …
