Polymers with flexible chains, such as natural rubber (NR), have low Tg values. The Tg is always less than the Tm> and the ratio of Tg to Tm is lower for symmetrical polymers like polyvinylidene fluoride (PVDF) than for those with unsymmetrical repeating units, such as polychlorotrifluoroethylene. Raymond Boyer has proposed a relationship of Tm — KTg, where the constant K — 2 for symmetrical and 1,4-asymmetrical chains.

Dow also became interested in the production of polystyrene and in addition to its cellulosic and vinylidene chloride projects, also supported a project on polystyrene. One of the polymer pioneers, who was responsible for the commercialization of polystyrene at Dow, was Raymond Boyer. Dow produced polystyrene commercially in the US in 1935. Both IG Farbenindustrie and Dow used the Berthelot synthesis for the production of the styrene monomer. 

Chemical played a leading role. The classic monograph edited by Ray H. Boundy (1902-1992) and Raymond F. Boyer (1910-1993) on Styrene Its Polymers, Copolymers and Derivatives was commissioned in this laboratory [19],... 

Transitions and Relaxations in EPST 1st ed., Suppl. Vol. 2, pp. 745-839, by Raymond F. Boyer, Midland Macromolecular Institute in EPSE 2nd ed., Vol. 17, pp. 1-22, by John T. Bendler, General Electric Company. 

This interim report presents the current state of our knowledge and speculation regarding the thermoreversible gelation of atactic polystyrene, and the broader implications to thermoreversible gelation of crystallizable polymers. Since we first reported the phenomenon in 1979, considerable interest has been stimulated as the implications for both the solution and solid states have been recognized. The early interest and subsequent contributions of Dr. Raymond F. Boyer makes this a particularly timely occasion for this review. 

This paper is dedicated to Prof. Raymond F. Boyer on the occasion of his 75th birthday. 

Various instrumental methods have been applied or developed to study liquid state transitions. All of the methods discussed in this paper stem directly from collaborations between Raymond F. Boyer and various researchers at MMI over the period 1975 to 1985. For the sake of brevity, the emphasis in this review will be on T>Tg transitions in amorphous styrenic polymers. The reader is referred to the article by Boyer for a discussion of liquid state transition studies for a... 

Again, the focus of this article will be slanted toward liquid state transition studies conducted at MMI over the past decade under the auspices of Raymond F. Boyer. For a discussion of the international research effort in this area, going back to the early 1940s, the reader is referred to the extensive review article by Boyei that has recently appeared. 

The author is indebted to Prof. Raymond F. Boyer for launching his career in polymer transition studies and for over a decade of fruitful collaborative research in this area. Further, R.F. Boyer has been the driving force behind all of the liquid state techniques developed at MMI and discussed in this paper. 

The author is indebted to Raymond F. Boyer for his patience and guidance in this endeavor and wishes to congratulate him on the occasion of his 75th birthday. Kudos to Steven E. Keinath for his constructive criticism and valuable discussions in the course of this work. Thanks also go to Lu Ho Tung of the Dow Chemical Company for the donation of polystyrenes PS-55 and PS-118. 

Proceedings of the 17th International Symposium on Order in the Amorphous State of Polymers, held August 18-21, 1985, in Midland, Michigan —T.p. verso. Dedicated to Raymond F. Boyer in honor of his 75th birthday. 

This volume is dedicated to Dr. Raymond F. Boyer, Research Professor of Polymer Physics and Affiliate Scientist at the Michigan Molecular Institute, in honor of his 75th birthday and lOth anniversary at MMI. 

When Ray Boyer joined MMI in 1975 upon his retirement from a very successful 40-year career at the Dow Chemical Company, he had some 90 publications to his credit. By 1985, after one short decade at MMI, he had nearly doubled this figure, primarily vyriting and publishing in the area of polymer transitions and relaxations, in particular, transitions in the liquid state. Boyer was named as Honorary Chairman of the Symposium from which this proceedings volume is derived in recognition of his pioneering research effort in this area. It is both fitting and proper for this volume to be dedicated to Dr. Raymond F. Boyer.
