Chemistry and Properties of Phenolic Resins and Networks

January 1, 2003
Author(s)
Sheng Lin-Gibson, J S. Riffle
This book chapter emphasizes the recent mechanistic and kinetic findings on phenolic oligomer synthesis and network formation. The synthesis and characterization of both novolac and resole type phenolic resins and their resulting networks are described

Chemistry of Silanes Interfaces in Dental Polymers and Composites

January 1, 2003
Author(s)
Joseph M. Antonucci, Sabine H. Dickens, Bruce O. Fowler, H H. Xu, Walter G. McDonough
The performance and service life of glass- or ceramic-filled polymeric composites depend on the nature of their resin, filler and interfacial phases as well as the efficacy of the polymerization process. The synergy that exists between the organic polymer

Chitosan Hydrogels Crosslink Kinetics and Gel Properties

January 1, 2003
Author(s)
Sheng Lin-Gibson, H J. Walls, S B. Kennedy, E R. Welsh
Cure kinetics and network properties of biocompatible hydrogels prepared by the reaction of chitosan and a water soluble blocked diisocyanate have been measured using rheometry. The reactions follow the Arrhenius behavior from which apparent activation

Clock Jitter Estimation based on PM Noise Measurements

January 1, 2003
Author(s)
David A. Howe, T Tasset
"Jitter" is the noise modulation due to random time shifts on an otherwise ideal, or perfectly on-time, signal transition. In the absence of ultra-high-speed jitter analyzers, spectrum analysis is an alternate noise measurement for timing jitter
