Polymers, Rheology and Processing

This web site is about a range of  subjects on  Polymers, Plastics, Rheology and Processing. For example, the very visual movie clips on this page show in one case, stress fields in flowing molten polyethylene plastic and  the second movie shows how water filaments break up when subject to very high stretching extensional strain rates. The site will prove useful to  people who want to learn about a range of topics that are covered and to more specialist scientists and engineers.

There are specific sections on;

  Polymers,   Rheology,   Fluid Mechanics,   Innovative Processing,   Scientific ApparatusThe Sustainability of Plastics.  Something to Say” and Publications.

You will find short introductions to each of the headline topics followed by a selection of  presentations that describe different aspects of the various scientific and  technological fields. There are also  my Cambridge University lecture notes on both;  

Rheology and Polymers

Recent work on droplet breakup carried out in conjunction with CEMEF at Sophia Antipolis, France, can be found at; 

Ink jet and filament stretch


Science, Engineering and innovation all have visual and creative parts and  some  aspects are covered in“Something to say”. The section includes short articles such as  how scientists and engineers can be thought of as creative people in addition to a range of topics that  could be classified as opinions rather than scientific facts. There is  a cluster of very visual Movie clips  ,again most of the movies involve flow describing various processes and experiments.  I have also added a recent section on plastics use and reuse;

The Sustainability of Plastics.


Something new!

Stretching Rheology and Symmetry to the limits!

   Covid-19 has resulted in an Institute for Non Newtonian Fluid Mechanics (INNFM) Port Merrion (Wales) meeting to be postponed and so below I include my contribution. The talk is a story that links my connections with Wales and highlights two areas of research carried out in the 1970s and the 2010s. There are notes for each slide

If you are looking for a scientific/technology story to read, why not try my fiction novel? The book was written in the 1990s with an epilogue added in the 2000s. I wonder if you can pick up how the world had changed between these dates, even after such a short

The scientific research described in this web page has either been created by myself or an army of Postoctoral or PhD students working with me at Bristol, Sussex, CEMEF (France) and Cambridge. I am indebted to all their talents in contributing to this work and acknowledge their invaluable contribution. Any publications that appear on this web site are for educational purposes only.
