Palierne's emulsion model is utilized to develop a linear viscoelastic model for the rheological description of matrix/core-shell modifier blends with strong adhesion at the particle/matrix interface. In this model, the total stress is assumed to be the sum of a mean stress and an additional mean st
## Abstract The grafting of a vinyl monomer, methyl methacrylate (MMA) or styrene (ST), onto a natural rubber (NR) exhibited a coreβshell structure, with NR as the core and poly(methyl methacrylate) or polystyrene as the shell. The grafting efficiency (GE) of the graft copolymer was determined by a
A method to obt,ain the diffusion coefficients and free volume parameters from desorption data for organic liquids in polymer films is presented. The method c0nsist.s of fit,ting a numerical solution of the diffusion equation to experimental desorption data. Some problems that arise in the solution
When a polymer is in contact with a liquid, the liquid may enter the polymer, the process being controlled by transient diffusion, with subsequent swelling. A mathematical treatment cannot be made under these conditions, and a numerical treatment must be used. Generally, a framework of reference wit
