A nonaqueous potentiometric titration study of the dissociation of t-butyl methacrylate-methacrylic acid copolymers.
The dissociation of t-butyl methacrylate-methacrylic acid copolymers in dimethyl sulfoxide was analyzed by a nonaqueous potentiometric titration technique. The negative logarithm of the dissociation constant of the monomer unit of a methacrylic acid (MAA) monotonously increased with the increasing degree of dissociation corresponding to the titrant/MAA amount ratio, and was highly influenced by...
متن کاملMODELING DRUG RELEASE FROM DYNAMICALLY SWELLING POLY(HYDl?OXYETHYL METHACRYLATE-CO-METHACRYLIC ACID) HYDROGELS
Drug release from a swelling hydrogel matrix is a complicated process where diffusion of drug molecules is coupled to the swelling kinetics. The swelling influences the diffusional flux of drug molecules by increasing the diffusion coefficient and diffusional pathlength. Release of phenylpropanolamine from apoly(hydroxyethy1 methacrylate-co-methacrylic acid) hydrogel, initially at low pH, is hi...
متن کاملThermal characteristics of the self-healing response in poly(ethylene-co-methacrylic acid) copolymers.
A class of poly(ethylene-co-methacrylic acid) (EMAA) copolymers and ionomers has shown the unique ability to instantaneously self-heal following ballistic puncture. It is noteworthy that the thermomechanical healing process active in these materials appears to be significantly different in capability and mechanism than any of the other self-repairing systems studied. To better understand this p...

متن کاملAssociation Behavior of Poly (methyl methacrylate-b-methacrylic acid-b-methyl methacrylate) in Aqueous Medium
ABA type tri-block amphiphilic polyelectrolyte consisting of poly(methyl methacrylate-block-methacrylic acid-block-methyl methacrylate) (P(MMA-b-MAA-b-MMA)) was synthesized by atom transfer radical polymerization technique (ATRP) and the self-assembly behavior of the polymers in aqueous solution was studied over the course of neutralization. Combination of potentiometric and conductometric tit...
