Curing process of benzoxazine systems. An experimental and theoretical study

Mostrar todas las versiones(2)

"A mathematical model that simulates the curing process of benzoxazine (Bz) systems is presented. The model predicts the conversion, gel point and Tg along the curing process, and considers the diffusional limitations to mass transfer due to the increase in the system viscosity along the proces...
