You are invited for the Brightlands Science Lectures on Monday, February 11, 2019. This Lecture will be presented by Professor Alejandro J. Müller (Professor at the Institute for Polymer Materials (POLYMAT) and at the Polymer Science and Technology Department, Faculty of Chemistry, University of the Basque Country UPV/EHU in Donostia-San Sebastián, Spain).

Lecture Professor Alejandro J. Müller 
'Templating crystallization in double and triple crystalline melt miscible copolymers and terpolymers'
From all commercially available polymeric materials, approximately 75% are semi-crystalline. Copolymers consisting of crystalline components show a complex interplay between morphology, nucleation and crystallization. Understanding and controlling their crystallization behavior allow tuning properties, such as gas permeation, mechanical properties, biodegradation (when dealing with biodegradable components), etc. Several examples of morphological self-assembly of copolymers, as well as their nucleation and crystallization properties, will be addressed in this lecture.

'A critical note on the use of time-temperature superposition for lifetime predictions in polypropylene pipes'
Companies like SABIC have to certify the time dependent behavior of their materials and guarantee long life times at certain loading conditions. Of course, 50 years is far too long for direct testing and because of that, a standardized procedure based on time-temperature superposition (TTS) is typically used for life-time evaluation. This procedure lacks some important features in case of application to polypropylene pipes. In this study, it is shown how the lack of these aspects can corrupt the TTS procedure and result in premature product failure or erroneous life-time estimations, and thus eventually harm society and economics.

Read the biography of Professor Alejandro J. Müller and Harm Caelers.
