Additives in Polymers

This industrially relevant resource covers all established and
emerging analytical methods for the deformulation of polymeric
materials, with emphasis on the non-polymeric components.

• Each technique is evaluated on its technical and industrial
  merits.

• Emphasis is on understanding (principles and characteristics)
  and industrial applicability.

• Extensively illustrated throughout with over 200 figures, 400
  tables, and 3,000 references.

Texte du rabat
Designed to inspire analytical chemists, polymer and material scientists, graduates and post-graduates, laboratory technicians and other practitioners working for industry, academia, government and regulatory agencies concerned with plastic products, this title provides systematic coverage of the latest instrumental methods for monitoring, deformulation and troubleshooting with an emphasis on additive analysis. The book is extensively illustrated with figures, flow diagrams and tables to facilitate a rapid understanding of this topic and the many thousands of references make this text an invaluable and up-to-date-guide. Current analytical strategy and best practice of this highly multidisciplinary field are outlined and illustrated with key industrial applications and case studies. Detailed coverage comprises sample preparation, separation, identification, hyphenation and quantification techniques, and much, much more
