The role of cationic monomers in chrism polymerization
[2-(methacryloyloxy)ethyl] trimethylammonium chloride (MATMAC), and vinylbenzyl trimethyl ammonium chloride (VBTMAC) were called to be acclimated as ionic comonomers in the chrism polymerization of styrene.
The cationic attributes of the two comonomers is the aforementioned (quaternary ammonium salts), about the styrene acquired (VBTMAC) is added berserk than the methacrylic one (MATMAC). With the added berserk cationic comonomer (VBTMAC) college conversions were acquired due to the in situ conception of an amphiphilic copolymer with styrene and faster ante of polymerization were empiric by accretion the cationic comonomer concentration.
The aforementioned behavior was empiric with the added hydrophilic cationic comonomer (MATMAC) at concentrations up to 0.012 M. At college concentrations the ionic backbone controls the colloidal adherence of the arrangement and agglomeration occurs.
