(2003) showed that filmogenic polymers used in enteric coating of capsules were cellulose acetate phthalate and methacrylic acid
copolymer which were only soluble in intestine fluids as from pH 6.0.
The native silk fibroin has proved to be cytocompatible with both animal and human cells, and the methacrylic acid
grafting has improved its cell adhesion property.
This formulation contained 0.3261 g of SDM2, 0.2383 g of methacrylic acid
, 0.0271 g of Irgacure [R] 819, and the same small amount of Irganox [R] 1330 plus the stabilizers contained in the SDM2 and methacrylic acid
salts of other metal centers did not produce significant activation, consistent with previous work investigating alternative metal oxide/stearic acid complexes.
It contains methacrylic acid
, a very corrosive substance.
For instance, methacrylic acid
linked up in repeating units to form a polymer cage around the drug molecule, while a chemical cross-linker called ethylene glycol dimethacrylate strengthened the cage.
Methyl methacrylate is one of the most prominent esters of methacrylic acid
. It is a volatile, colourless and flammable liquid with moderate solubility in water.
The phosphate/acrylate copolymer is a co-polymerized product of a mixture of acrylic acid, methacrylic acid
, and a mixture of 2-hydroxyethyl methacrylate phosphates.
Acrylic acid esters and methacrylic acid
esters typically show the monomer as a significant, if not primary, pyrolysis product.
A small proportion of methacrylic acid
was used in the formulation reported by Menshikova et al.
N-isopropyl acrylamide (NIPAAm) (Aldrich, Milwaukee, USA), methacrylamide (MAm) (Merck, Darmstadt, Germany), methacrylic acid
(MA) (Merck, Darmstadt, Germany) and itaconic acid (IA) (Sigma, St.
