The electron impact mass spectra of several gem-bisamides are studied. The dominant peaks in the spectra of alkylidene and arylidene bisalkylamides are formed by the cleavage of the C -N bond of the amido group with charge retention on the nitrogen atom. This fragmentation, followed by the loss of a
N,N,NΠ,NΠ-tetraallyl piperazinium dibromide (TAP) has been prepared in high yields by quaternization of N,NΠ-diallyl piperazine with allyl bromide. Herein, we have described preparation of nonhydrolysable, strong, cationic hydrogels by copolymerization of TAP with N,N-diallyl morpholinium bromide (D
