EFFECT OF LOCATION OF POLYMERIZABLE DOUBLE-BOND ON THE POLYMERIZATIONOF MICELLE-FORMING MONOMERS

The polymerizability of micelle-forming quaternary ammonium monomers, which were derived from a methacrylic ester and styrene, carrying a po lymerizable double bond close to the head group (Type H) or at the alk yl chain end (Type T) including a new monomer, 5-(p-vinylphenyl)pentyl trimethylammonium bromide, has been investigated above their critical micelle concentrations in water. The results are explained on the basi s of the structure of the obtained polymers as well as the micelle str ucture of the monomers in water. The Type H monomers were able to ther mally polymerize, while the Type T monomers could not.
