✦ Synopsis

A new substituted diphenylamine diazonium salt, N-methyl-2-nitrodiphenylamine-4-diazonium salt (MNDDS) and its diazoresin (MNDDS-resin) were synthesized and their thermostability as well as photosensitivity were investigated. The results show that MNDDS and resin exhibit much higher thermostability than that of the parent compound, diphenylamine-4-diazonium salt (DDS) and resin (DDS resin) in solid state or in coating but the photosensitivities of them are confirmed to be in same level. The excellent thermostability of MNDDS and its diazoresin is very important because the storage life of a negative presensitized plate is mainly dependent on it.

Poly-␤-amides (nylons 3) were synthesized via the anionic polymerization of a series of 4-alkyl-4-methyl-2-azetidinones where the alkyl group is a methyl, ethyl, propyl, butyl, or pentyl. The "non-assisted" polymerization was conducted under vacuum, in the bulk, at 160°C, using potassium 2-pyrrolido
