11 New Improvement (2) Kinetics of Multi polymer System Networking reactions Key Concern of the Model: Model complexity Multiple reaction probability distributions from model sources Highly nonlinear structure Difficulties for efficient optimization 11
12 Possible Reactions in IPN System I* Grafting Intermolecular transfer Inter radical generation Possible growing and networking Network β scission Fig 5. Schematic Representation of the Nonlinear Reactions in the IPN System Free radical on chain B Free radical on chain hi A Grafted polymer Crosslinked polymer 12
13 Nonlinear Polymer Molecular Weight Cl Calculation lti Numerical fractionation Unableto model chain Instantaneous MWD method random scission Discrete weighted residuals Approximation functions of molecular weight distribution Monte Carlo simulation Difficult to optimization Double moment method Population balance approach Has not applied for polymer composite system 13
14 Decompose the Nonlinear Structure Separate representation for two polymers = + = + 14
15 Statistical and Sectional Grid Approach (1) analogy to Chain combination / breakup Particle breakup /aggregation Sectional grid approach Fixed pivot technique (Number and mass are preserved by set f(v) to zeroth and first properties) 15
16 Statistical and Sectional Grid Approach (2) Chain random scission: 16
17 Statistical and Sectional Grid Approach (3) Chain combination: 17
18 Statistical and Sectional Grid Approach (4) Nonlinear chain structure is recovered by statistical assemblage Position independent assumption Network fraction is classified by crosslinked chain length New model capabilities i Gel fraction / Gel composition Branching frequency Joint molecular weight distribution 18
19 Summary Single particle model has been improved in modeling particle growth Consistent agreement was observed in all studied cases Parameter ranking and subset selection are implemented for parameter estimation Kinetics of polymer composite is under study. More efficient modeling approach is proposed for further research 19
