Journal Article
Hutchings, L. R., Kimani, S. M., Hoyle, D. M., Read, D. J., Das, C., McLeish, T. C., …Auhl, D. (2012). In Silico Molecular Design, Synthesis, Characterization, and Rheology of Dendritically Branched Polymers: Closing the Design Loop. ACS Macro Letters, 1(3), 404-408. https://doi.org/10.1021/mz300059k

It has been a long held ambition of both industry and academia to understand the relationship between the often complex molecular architecture of polymer chains and their melt flow properties, with the goal of building robust theoretical models to pr...

Chain Deformation in Entangled Polymer Melts at Re-entrant Corners (2010)
Journal Article
Clarke, N., De Luca, E., Buxton, G., Hutchings, L., Gough, T., Grillo, I., …McLeish, T. (2010). Chain Deformation in Entangled Polymer Melts at Re-entrant Corners. Macromolecules, 43(3), 1539-1542. https://doi.org/10.1021/ma902324f

Using SANS to map the deformation of individual polymer chains in the vicinity of re-entrant corners in a contraction−expansion flow, we show that stress singularities at such corners, predicted by formulations of fluid dynamics that lack a molecular...

The long-chain dynamics in a model homopolymer blend under strong flow: small-angle neutron scattering and theory (2009)
Journal Article
Graham, R. S., Bent, J., Clarke, N., Hutchings, L. R., Richards, R. W., Gough, T., …McLeish, T. C. (2009). The long-chain dynamics in a model homopolymer blend under strong flow: small-angle neutron scattering and theory. Soft Matter, 5(12), 2383-2389. https://doi.org/10.1039/b817440g

We use small-angle neutron scattering (SANS) measurements to provide a detailed picture of the non-linear dynamics of the long chains in a model polystyrene blend. By a weighted subtraction of SANS measurements from two otherwise identical blends wit...

Neutron flow-mapping: Multiscale modelling opens a new experimental window (2009)
Journal Article
McLeish, T. C., Clarke, N., de Luca, E., Hutchings, L. R., Graham, R. S., Gough, T., …Chambon, P. (2009). Neutron flow-mapping: Multiscale modelling opens a new experimental window. Soft Matter, 5(22), 4426-4432. https://doi.org/10.1039/b916288g

Small-angle neutron scattering (SANS) has delivered significant insight into the rich and varied phenomena seen in the non-linear dynamics of entangled polymers. The lengthscales accessible by SANS are ideally matched to the strongly lengthscale-depe... Read More about Neutron flow-mapping: Multiscale modelling opens a new experimental window.

Measuring and predicting the dynamics of linear monodisperse entangled polymers in rapid flow through an abrupt contraction. A small angle neutron scattering study. (2006)
Journal Article

Measuring and predicting the dynamics of linear monodisperse entangled polymers in rapid flow through an abrupt contraction. A small angle neutron scattering study. Macromolecules, 39(7), 2700-2709. https://doi.org/10.1021/ma052357z

Small-angle neutron scattering measurements on a series of monodisperse linear entangled polystyrene melts in nonlinear flow through an abrupt 4:1 contraction have been made. Clear signatures of melt deformation and subsequent relaxation can be obser...

Constriction flows of monodisperse linear entangled polymers: Multiscale modeling and flow visualization. (2005)
Journal Article

We explore both the theology and complex flow behavior of monodisperse polymer melts. Adequate quantities of monodisperse polymer were synthesized in order that both the materials rheology and microprocessing behavior could be established. In paralle...
