Book Description
This report examines the state of knowledge and the future promise of guayule Parthenium argentatum Gray, a little known shrub native to the desert of southwest Texas and northern Mexico that was a commercial source of natural rubber during the first half of this century.This perennial shrub thrives in arid conditions and can survive heavy frosts. Guayule, after thorough drying, has been found to contain as much as 26% rubber. This rubber can be used to make vehicle tires or any other item currently made with natural rubber. It is a promising plant for use in reforestation of desert fringe lands and is easy to grow. Extraction of the rubber is not technically difficult; in fact, small-scale household extraction is possible. The plant can be cut down to the ground and will grow again from the roots.The book covers: background and history, botanical information, rubber extraction, agricultural production, rubber quality, economics, research needs, selected readings and recommendations.When guayule grows actively, it produces little or no rubber. If the plant is stressed, growth slows and the products from photosynthesis are diverted into rubber production. Thus when growth slows during cold weather or because of reduced moisture supply, the rubber content begins to increase.

Book Description
Biopolymers from Renewable Resources is a compilation of information on the diverse and useful polymers derived from agricultural, animal, and microbial sources. The volume provides insight into the diversity of polymers obtained directly from, or derived from, renewable resources. The beneficial aspects of utilizing polymers from renewable resources, when considering synthesis, pro cessing, disposal, biodegradability, and overall material life-cycle issues, suggests that this will continue to be an important and growing area of interest. The individual chapters provide information on synthesis, processing and properties for a variety of polyamides, polysaccharides, polyesters and polyphenols. The reader will have a single volume that provides a resource from which to gain initial insights into this diverse field and from which key references and contacts can be drawn. Aspects of biology, biotechnology, polymer synthesis, polymer processing and engineering, mechanical properties and biophysics are addressed to varying degrees for the specific biopolymers. The volume can be used as a reference book or as a teaching text. At the more practical level, the range of important materials derived from renewable resources is both extensive and impressive. Gels, additives, fibers, coatings and films are generated from a variety of the biopolymers reviewed in this volume. These polymers are used in commodity materials in our everyday lives, as well as in specialty products.

The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)
