Combining Process Rheology and Spectroscopy Measurements to Improve Batch Polyurethane Polymer Production
24 ژوئن 2021

In step-growth polymerizations, the degree of polymerization is strictly dependent on conversion and is very sensitive to impurities and molar imbalance, especially when conversion is high. Monomer imbalance may prevent the formation of long polymer chains (leading to molecular weight stagnation) and promote the occurrence of undesired secondary reactions (leading to chain branching, gelation and/or chain […]
