The effects of urea on aqueous solutions of both poly(methacrylic acid (PMA) and poly(acrylic acid) (PAA) have been investigated by using potentiometry, viscometry and study of the fluorescence of Auramine O, a cationic dye. The viscosity behaviour of unionized PMA obtained from direct dissolution o

## Abstract The effect of pressure (up to 6300 atm) on the electrical conductivity of poly(methacrylic acid) (PMA) in aqueous solution was investigated in the concentration range 0.001__M__ to 0.1__M__ (in equivalents of carboxyl groups) at 30Β°C. The degree of ionization Ξ± calculated from the condu
A convenient esterification reaction of poly(methacry1ic acid) (PMAA) with certain alkyl halides was performed using 1,8-diazabicyclo-[5.4.0] -7-undecene (DBU) as a base in aqueous solution or in water. The esterification reaction of PMAA with propargyl bromide (PB) proceeded very smoothly and quant
