The more fundamental aspects of fiber constitution and behavior are dealt with in Astbury s Fundamentals of Fibre Structure 27) and Textile Fibres under the X-Rays 28), Hermans Contributions to the Physics of Cellulose Fibres 39), and Physics and Chemistry of Cellulose Fibres (40 Marsh s Textile Science (40 Preston s Fibre Science 59) and the High Polymers series of monographs, three of which are concerned with natural fibers—Volume IV, Natural and Synthetic High Polymers, by Kurt H. Meyer 53), Volume V, Cellulose and Cellulose Derivatives, edited by Emil Ott 56), and Volume VI, Mechanical Behavior of High Polymers, by Turner Alfrey, Jr. 21 ... 

Dr. Mark was appointed head of the Shellac Bureau in 1939 and was promoted to a full professor in 1942. During the World War II years, Mark directed many research projects for the United States government. Among the many notable polymer scientists on his research teams were Drs. Turner Alfrey, Paul Doty, Isidor Fankuchen, W. Hohenstein, Arthur Tobolsky and B.H. Zimm. 

Symposium on Milestones and Trnids in Polymer Science and Technology A Tribute to Turner Alfrey, MMI, Midland, Michigan, June 6-9, 1983. 

As one can see by inspection of these two lists, there is a good geographical distribution, a modest industrial representation, but most of all a number of new faces, particularly from among the younger polymer chemists from both countries. A total of 63 papers were presented that were divided between the 24 invited lectures, 29 submitted papers, and 10 poster session presentations. Regrettably, Turner Alfrey, had a cancer operation just prior to the meeting and could not attend his paper was read by Harvey D. Ledbetter, from the Dow Chemical Company.

What is now known as the correspondence principle for converting viscoelastic problems in the time domain into elastic problems in the transform domain was first discussed by Turner Alfrey in 1944. As a result, the principle is sometimes referred to as Alfrey s correspondence principle. Later in 1950 and in 1955 the principle was generalized and discussed by W.T. Read and E. H. Lee respectively. (See bibliography for references.)... 

The fact that Eq. 8.3 can be considered as the equivalent of Hooke s law in the transform domain leads to a general method to solve many practical viscoelastic boundary value problems in a simple manner. This procedure is often attributed to Turner Alfrey and is sometimes referred to as Al-frey s correspondence principle. Simply stated the procedure is as follows ...

The monograph on mechanical behavior was written by Turner Alfrey, Jr. (1918-1981) and published as Volume 6 of the Interscience Series on High Polymers in 1948 [21]. At the time he was an Assistant Professor of Polymer Chemistry at the Polytechnic Institute of Brooklyn. He joined Dow Chemical in 1950 and spent his career there. Alfrey received his Ph.D. in Polymer Chemistry from Brooklyn Poly in 1943. He returned to Poly in 1945 after a stint with Monsanto (Fig. 3.16). 

Polymer science is a multidisciplinary community. While it is united by a love of macromolecules, each member also brings expertise from another community. The community of X-ray crystallographers contributed many of the early leaders in polymer science. Turner Alfrey was a member of the Society of Rheology and received its highest honor, the Bingham Medal, in 1954. In this monograph he combined his two loves in a monumental exposition of both rheology and polymer science.
