Description Usage Arguments Details Value Author(s)
The function calculate the change of kinetic constants due to gel effect
1 | gel(y, pars, roM, roS, roP)
|
y |
vector of material and energy balance, as supplied by the function |
pars |
vector of chemical-physical parameters, as supplied by the function |
roM |
function of monomer density (Kg/L) vs. temperature (K) |
roS |
function of solvent density (Kg/L) vs. temperature (K) |
roP |
function of polymer density (Kg/L) vs. temperature (K) |
The function evaluate the reduction of kinetic constant of propagation, termination, initiation when gel effect take place. Several models are implemented: diffusional, segmental and reactive. User can choose among them by menu choice
A list with the following elements:
Kt decrease of bimolecular termination constant by diffusional model
Kp decrease of propagation constant by diffusional model
Kd decrease of initiator factor efficiency by diffusional model
Kts decrease of bimolecular termination constant by segmental model
Ktrmin minimal decrease of bimolecular termination constant by segmental model
Ktrmax maximal decrease of bimolecular termination constant by segmental model
