"The sciences as a whole are slowly but gradually drifting away from life and are only returning after adetour". Goethe Detours should be avoided. The picture we are presenting here of the current theory in phenolic resin chemistry and the technical application of phenolic resins is based on day-to-day experiences in research, pro4uction and marketing, however, with the background of economic relevance. This book, then, is not to be regarded as a systematic collection and evaluation of the literature, although the literature up to July, 1978 has generally been taken into consideration. The audience to which this book is directed is wide-ranging: chemists, engineers, marketing professionals and students. We show where the first fully synthetic polymers, phenolic resins, stand today and what their future iso Taking a look back over their development, one is only more deeply convinced that after a wide variety of adaptions, they still possess the tech­ nical and economic strengths which allow for their further market growth and with it, a full appreciation of their value. We would like to extend our gratitude to all friends and promotors, in particular to those who helped and encouraged us with advice and assistance.

A backward glance of the many new industries that emerged in the 20th century would surely recognize communications, automobile, aircraft, computer and several others that have had a global impact on world economy. Yet another industry, and an often neglected industry, made its debut early in the 20th century - the Plastics Industry. The Plastics Industry owes its identity to the brilliance of Dr. Leo Hendrik Baekeland (1863 -1944). He discovered the technique, currently in use to this day, to manu­ facture highly crosslinked plastics by transforming monomerk and/or oligomeric phenolic materials into attractive phenolic products. Today phenolics represent one of the many different types of com­ mercially available plastics (thermoset and thermoplastic). Phenolics are distinguished by a broad array of application areas that utilize phenolics as compared to other thermoset or thermoplastic resins. Thermoplastic resins transformed into molded products, films or synthetic fibers (polypropylene as an example) are rapidly recognized as "plastics" whereas the phenolic resin is a component in a material system and the identity of the phenolic resin within the system is not easily identified as "plastic". These systems consist of fiber reinforced composites, honeycomb paneling, electrical Iaminates, acid resistant coatings, wood panels, glass fiber or rock wool insulation. Phenolic resin identity is hidden and has little consumer recognition or identity.
