This book is the foundation treatise in this emerging field of combined chemistry, physics, mathematics and engineering. It reviews experimental techniques and results, theoretical ideas and reviews the foundations of the field. - ;Liquid crystals are fluids with a directionality defined. Polymers are long molecules with a shape that can be changed. As a network, polymers form rubber - a soft solid that is locally liquid-like and capable of huge extension.
