PREFACE TO THE PRINT EDITION. e; c b2 u/ |2 e
The Polymer Data Handbook offers, in a standardized and readily accessible tabular format, concise

for selecting the polymers included in this volume. The first criterion was current commercial

The hope is that some readers will become interested enough in these newer materials to contribute to# p! f( u: P! {3 d. ^' L6 B
their further development and characterization. Finally, the handbook includes some polymers simply

effects of chain stiffness, self-assembly, or biochemical processes.

surface and interfacial properties, pyrolyzability, electrical conductivity, nonlinear optical properties,, _5 X" s5 z5 P; ?" J9 G+ b
and electroluminescence. Not all the properties are available for all the polymers included, and some/ E+ l V, ?1 F; L9 S# O% n
properties may not even be relevant for certain polymer classes. Some polymers exhibit properties3 a Y/ Q" a" D2 c, u1 A# p ]

Grateful acknowledgment is made here to the important contributions of the anonymous referees. It is
