Photoresists, electron and X-ray resists are generally mixtures based on organic polymers and radiation sensitive materials. Research and development of these mixtures is complicated and may be solved only in mutual collaboration between organic and physical chemistry, polymer chemistry, high energy and semiconductor chemistry and physics, as well as other branches of science. Research projects concerning the development, fabrication and application of resists necessitate systematic basic and applied research, increased effort on the part of research workers, and especially critical evaluation of the facts known to date and experimental results. All this has been borne in mind in the writing of this volume, the aim of which is to summarize and evaluate recent results of resist investigation and applications. Special attention is given to processes influencing the properties and quality of off-set plates, such as types of substrates and their coating, exposure, development, adhesion to substrate, hydrophobicity, etc.

This book is part two of a 3-volume series on polymers from renewable resources. The entire set focuses on gathering contributions from the leading workers in specific areas of research pertaining to this field, such as agroproteins, modification of natural polymers, and environmentally benign synthesis and processing. Each book is an up-to-the-minute guide on a wide range of the studies in this emerging field from polysaccharides to polyesters, biostable polymers to the regulatory issues that are critical to the development of new commercial biodegradable products.

This book is a collection of the addresses of the keynote speakers and invited lecturers as well as manuscripts of a few outstanding papers which were delivered at the First Pacific Polymer Conference organized by the Pacific Polymer Federation in Maui, Hawaii, 12-15 December, 1989. The First Pacific Polymer Conference covered a wide variety of topics in macromolecular science, demonstrating the emphasis given to polymer research in the Pacific Rim countries. The keynote speakers and invited lecturers are excellent scientists and leaders of effort who covered their fields expertly and in many cases gave their own perspective on the future of polymer science and engineering. A panel discussion on the role of polymers in the arts interested the attendees and emphasized the pervasiveness of polymers in all facets of life. The meeting was attended by over 500 scientists from all over the world. The participants left the meeting with renewed feeling for the importance of polymers in the material sciences and impressed by the progress in polymer research and development. This book, therefore, provides a wide -angle snapshot of the polymer research as we enter the 1990's. It is a useful book for all scientists interested in polymers and the progress of our science in the countries of the Pacific Rim. We hope that many attendees were stimulated by the meeting and that new ideas and new collaborations will result which will further enrich research, and lead to new useful polymers for all countries.
