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 کاملAcrylic acid and methacrylic acid based hydrogels-A review
Hydrogels are three-dimensional polymeric networks those swell quickly by imbibing a large amount of water or deswell in response to even miniscule changes in their external environment. The water uptake or swelling may be thousands of times of their initial volume in water. The volume phase transitions as a response to different stimuli make these materials interesting objects of scientific ob...
متن کاملInteraction of Tetradecyltrimethylammonium Bromide with Poly(acrylic acid) and Poly(methacrylic acid). Effect of Charge Density
The effect of polymer chalge density on the interaction of tetradecyltrimethylammonium brolnide <TrAB) with poly(acrylic acid) (PAA) and poly(methacrylic acid) (PMA) has been investigated usmc a surfactant-sensitive solid-state membrane electrode. The experimental results indi~te that the intenction with PAA begins at about the same equilibrium TTAB concentration wben the degree of ionization (...
متن کاملDirect synthesis of ethylene-acrylic acid copolymers by insertion polymerization.
Neutral palladium(II) phosphinesulfonato polymerization catalysts were found to be stable toward carboxylic acid moieties and to enable direct linear copolymerization of ethylene with acrylic acid.
متن کاملNo contact allergy to acrylic acid and methacrylic acid in routinely tested dermatitis patients.
Occupational and non-occupational contact allergy to, and allergic contact dermatitis caused by, acrylates/methacrylates are frequently reported (1–18). However, there is no acrylate/methacrylate test preparation in the European baseline patch test series (19). Therefore, contact allergy to, and allergic contact dermatitis caused by, acrylates/methacrylates may be overlooked when the decision i...
