Library of Congress Topics in Preservation Series (TOPS)

The Preservation Directorate of the Library of Congress announces
the 44th presentation in the Topics in Preservation Series (TOPS):

"Towards a Multi-Functional Mass Deacidification Process Using
Aminoalkylalkoxysilanes"

Pickford Theater
3rd floor James Madison Building
Friday, May 8, 2009
10:30-11:30 am

Professor Herve Cheradame will discuss his current research on the
use of aminoalkylalkoxysilanes in paper conservation. Several
experiments will be described, leading to discussion of the role of
the structure of the molecule responsible for the deacidification
effect and the improvement of mechanical properties, as well as the
role of residual moisture and the role of the solvent in paper
deacidification. Potential implications for the use of
aminoalkyalkoxysilanes for a mass scale deacidification process will
be discussed.

Professor Herve Cheradame, Emeritus Professor of the University of
Evry and Vice President of the Centre de Conservation du Livre in
Arles, France, is a specialist in the area of polymer synthesis and
properties.

Webcast opportunity:  If you would like to participate via webcast,
