CYCLOPOLYMERIZATION .8. POLYMERIZATION OF "SYM-DIMETHACRYLOYLDIMETHYLHYDRAZINE AND RELATED COMPOUNDS

Polymerization behaviors of several 1, 7-dienes were investigated in order to see the correlation between their cyclopolymerizability and the polymerizability of their monofunctional counterparts. In connection with this problem, studies on the effect of the intermolecular hydrogen bonds between monomers or between a monomer and a solvent on the cyclopolymerizability of these dienes have also been undertaken. sym-Dimethacryloyldimethylhydrazine, whose monofunctional counterpart does not polymerize, showed high cyclopolymerizability irrespective of the solvents used. sym-Dimethacryloylhydrazine and sym-diacryloyldimethylhydrazine, whose monofunctional counterparts polymerize, showed low cyclopolymerizability, though their ability to form hydrogen bonds is extremely different. The results thus obtained support the idea that the high and low cyclopolymerizabilities of these monomers are mainly associated with the low and high polymerizabilities of their monofunctional counterparts, respectively, but not with the ability to form hydrogen bonds, in agreement with the theory proposed previously. © 1979, The Society of Polymer Science, Japan.
