Polydiacetylenes

The polydiacetylenes are a class of polymers that are attrac­ ting increasing attention worldwide. There are many reasons for this interest one of the most important being the availability of many polydiacetylenes as macroscopic, high quality, single crystals. This fact was first reported in the pioneering work of Prof. G. Hegner on the solid-state polymerization of disub­ stituted diacetylenes in...
