Polymer Processing: using synchrotron radiation to follow structure development in commercial and novel polymer materials

Exploring the macro and micro-structure development associated with crystallization in polymer materials such as polyethylene and polypropylene can be achieved using Small-and Wide-Angle X-ray Scattering techniques (SAXS/WAXS). Here, SAXS probes the long range ordering or macrostructure and WAXS gives information on the atomic level of ordering (microstructure). Following structure development ...

Introduction to Polymer Database PoLyInfo

PoLyInfo is the generalized database system of synthetic polymers, which provides various facts required for material design; chemical structures, several types of name including IUPAC structure based name and source based name, about a hundred kinds of physical properties, monomers/polymerization information, and so on. Main data sources of PoLyInfo are a wide range of scientific journal artic...

Infrared Spectroscopy and Polymer Structure

INTRODUCTION The power of infrared spectroscopy as a tool in studying the structure of small molecules is well known. This insight into structure results largely from our ability to analyse the spectrum theoretically by means of a normal coordinate analysis. This technique consists of calculating the normal vibration frequencies of a molecule from information on its structure and internal force...

Trends in polymer development.

Polymer science and technology has flourished as polymers with many new compositions have been, synthesized. The range of properties attainable has been continually extended, providing materials with higher strength, better reinforcing capabilities, and greater resistance to extreme thermal and corrosive environments. Examples of evolutionary developments in the polyamides, the fluorocarbon res...
