Abstract
AMBER for decorative purposes, shellac in the electrical industry and for gramophone records, copals for varnishes, rosins in soaps: all are natural resins. The importance of the part they play in the daily economy of the world is obvious; indeed, at least half a million tons of them are used annually. Latterly, they have been supplemented and even substituted at a rapidly increasing rate by substances made artificially by the systematic exploitation of numerous organic chemical reactions. Such products have many new economic potentialities, particularly since, with increasing experience, the control of the reactions which produce them becomes more accurate, so that the possibility is offered of varying their properties widely and of increasing desirable qualities to a degree impossible with natural products. Already some forty thousand tons of synthetic resins are produced annually.
