Abstract: NEW MATERIAL:A diacetylene derivative expressed by formula I (X is NH or O; m is 8-20; n is 4-20). EXAMPLE:4-(10,12-Pentacosadiynylcarbonylamino)-2,2,6,6-tetramethylpipe ridine-1- oxy. USE:A diacetylene monomer, capable of forming paramagnetic polydiacitylene crystals in 100% radical concentration and utilized as a standard marker, antioxidant, radical scavenger, etc., since the monomer has stable radicals and exhibits solidphase polymerizability. PREPARATION:A diacetylenecarboxylic acid compound expressed by formula II and a stable radical compound expressed by formula III are subjected to dehydrating condensation reaction using dicylohexyldicarbodiimide to afford the aimed compound expressed by formula I.
