The zinc salts of acrylic and methacrylic acids also increase the adhesion strength of composites containing these coagents to more polar substrates.
The methacrylic acid content of the sodium ionomer is 10 mole percent, which is approximately 53% neutralized by sodium [27].
In order to achieve these goals, we have modified the natural silk fibers by grafting poly methacrylic acid (PMAA) and the modified surface was characterized using analytical techniques For the preparation of surface modified silk fiber with C=O functional group the silk square pieces were immersed in a solution of methanol and methacrylic acid with a ratio of 2:1.

When using functional monomers such as methacrylic acid or hydroxyethyl methacrylate, protective groups must be attached for successful synthesis.
Carboxylation of NBR with acrylic or methacrylic acid provides additional sites for crosslinks.
The microfiber is made of at least 10% by weight of a copolymer of ethylene, 5-25% of methacrylic acid and up to 40% of an alkyl methacrylate that has from 1-8 carbon atoms and 570% of the acid groups neutralized with metal ions.
Plastic Flamecoat grinds and colors its own proprietary coating powders with 400-600% elongation, using Du Pont adhesive resins such as Nucrel ethylene methacrylic acid (EMAA), Surlyn EMAA ionomer, and EVA, which are sprayed at 150-170 F.
The report will be of considerable interest primarily to relevant strategic planners, senior company officials and importers/exporters, since it features invaluable information on esters of methacrylic acid export/import operations segmented by country and region.
The formula also comprises at least one aqueous dispersion of particles of a polymer obtained by polymerization or copolymerization of monomers selected from the group consisting of styrene, vinyl acetate, urethanes, acrylic acid, methacrylic acid, and crotonic acid; at least one acrylamide/sodium 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonate copolymer polyelectrolyte, which is different from the polymer in aqueous dispersion; at least one surfactant with an HLB of greater than or equal to 6.
