An analysis of molecular parameters governing phase separation in a reacting polyurethane system
The evolution of microstructure in polyurethane foams is a complex process involving competing kinetics of polymerization, crosslinking, and phase separation. Hard segments form in-situ and the increase in molecular weight induces phase separation. Coincident with these processes is a significant ri...
