Food packs, containers, toothpaste tubes, wheels, glue, paints ... they are all made of polymers. The world of polymers is infinite and, so, there is a great variety. The majority have been designed for a specific application; given that at times the application might be for a food container and, at others, for the superstructure of a vehicle. The specifications needed in either case are quite different.
Polymers are gigantic molecules, but they are synthesised from small compounds: monomers. In fact, the name of the polymer normally indicates from which monomer it has been synthesised. For example, polystyrene (PS) is obtained from styrene, polyvinyl chloride (PVC) from vinyl chloride, etc.
But not polystyrenes are the same. Depending on the length of the monomer chain or on the mode of synthesis or processing, the final result can vary. Thus, before analysing any polymer, it is necessary to characterise it thoroughly.

Goodbye, silicon? On the way to new electronic materials with metal-organic networks
17.10.2018 | Max-Planck-Institut für Polymerforschung
Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
