CEEES Publication No 6 - Natural and Artificial Ageing of Polymers 2nd European Weathering Symposium, ISBN 3-9808382-9-3

This book was compiled from papers given at the 2nd European Weathering Symposium held in Gothenburg in June 2005. The hard backed book was published by GUS in 2005 and comprises 387 pages.

Launched in 1967 by four relevant institutes from Austria, Czechoslovakia, Hungary, and Yugoslavia, the Colloquia of Danubian Countries have been the only independent meeting - meanwhile Europe-wide - in the field of natural and artificial weathering of polymers for nearly 40 years. In the tradition of these colloquia the EWS is a meeting point for experts from industry and academy to learn from each other.
