Carvedilol was supplied by Dr. Reddy s Laboratory, Hyderabad, India as a gift sample. Poloxamer F68 and F127 were supplied by Lupin Research Park, Pune, India. All other chemicals used were of analytical grade. 

Polymer Samples. The poly(vInyl alcohol) (PVA) is a commercial material from Scientific Polymer Products. The sample was dissolved at 10 w/v in OMSO-c. The sample of vinylldene chloride isobutylene copolymer was a kind gift of Drs. R. E. Cais and F. A. Bovey at AT T Bell Laboratories in Murray Hill, NJ. The sample was dissolved at 20 w/v in CDCI3. 

The authors are grateful to the individuals mentioned in footnotes of Tables I and II for their gifts of the various polymer samples used in this study. 

This work was partially supported by a grant from the Research Corporation and by the Donors of the Petroleum Research Fund administered by the American Chemical Society. Early work was supported by the National Institutes of Health (GM 30147), while instrumentation and theoretical development have been supported by the National Science Foundation. Much work described stems from the research of a number of postdoctoral and graduate student co-workers, whose names are noted in the cited references. Many of the samples for special applications came to us as gifts or via collaborations with researchers from around the world, most of whom are also coauthors in the publications. 

Special thanks are due to Q.O. Chemicals for a generous gift of diol 10 and to Drs. Borredon, Delmas, Gaset and Rigal for providing precious samples of several monomers among those cited in this work. 

The polytrimethylene oxide sample was a gift from Professor J. E. Mcirk. Its viscosity average molecular weight was 100,000.

Physicians codes, guidelines and policies on receiving gifts and drug samples... 

As outlined above, some professional organizations are more specific than others. However, the general theme appears to be that while minor gifts, entertainment, and drug samples should not be solicited they may be acceptable if they directly promote better patient care or indirectly promote education or research and, in either case, do not affect the integrity of the physician-patient relationship. 

It is a pleasure to acknowledge the continuing advise, help, encouragement and gifts of numerous samples by Mr. H. A. Willis (I.C.I. Plastics), Dr. P. Holliday (Courtaulds Ltd.), Dr. P. R. Sewell (Dunlop Rubber Co., Ltd.) and many, many others. Professor D. Hummel has been kind enough to make a careful study of the manuscript and make a number of very helpful suggestions. 

Samples Studied. From British Seams. The suite of samples was collected and separated by the Coal Survey of the National Coal Board under the direction of Dr. G. W. Fenton, and the authors are indebted to Dr. Fenton for the gift of the samples. The suite consisted of the vitrinites, spore-rich exinites, fusinites and, in one case, the micrinite from five British coal seams of Carboniferous age together with the vitrinites from two coals of higher rank from which it was impracticable to separate the other macerals. The exinites were separated by float-and-sink methods from selected black durain bands, as also... 

The authors thank B. Imelik, M. V. Mathieu, and Y. Trambouze for encouragement. They are indebted to the I.R.C. laboratories of chemical and x-ray analysis and to R. Beaumont for the gift of two samples. Special thanks are due to M. C. Bertrand for help with the IR experiments. 

The alkali metals were obtained from the following sources sodium— J. T. Baker potassium—Mallinckrodt rubidium—Fairmount Chemical Co. cesium—a gift from the Dow Chemical Co. and lithium—Lithium Corp. of America. The lithium was washed with dry benzene and cut in a dry box when necessary. The other metals were cleaned, cut, and then degassed and distilled under high vacuum. Repeated vacuum distillations were used to obtain small metal samples in... 

We are grateful to the General Electric Co. for gifts of samples. This work was supported by AFOSR Grant 68-1434 (FEK) and NSF Grant GP 8581 (WJMacK). Acknowledgment is made to the donors of the Petroleum Research Fund, administered by the American Chem-...
