Chitosan (Fluka, middle viscous, 200-400 mPa-s), itaconic acid (Fluka) and methacrylic acid
(Sigma A.G.) were used for hydrogel synthesis.
As BZF has an amino group, methacrylic acid
(MAA) has been selected as a functional monomer.
Velickovic, Removal of Model Cationic Dye by Adsorption onto poly(methacrylic acid
)/Zeolite Hydrogel Composites: Kinetics, Equilibrium Study and Image Analysis, Sep.
When the solution was allowed to cool to ~37C, the appropriate amounts of ascorbic acid (0.352 g in 50ml of water), copper sulphatepenta-hydrate (CuSo4.5H2O) (0.2 g in 30 ml of water) and 90g of methacrylic acid
were added to the flask.
Therefore, it was selected to be further coated with poly(methacrylic acid
) (PMAA), as the outermost layer to improve its properties.
In addition, acetone is used in the manufacture of methyl methacrylate (MMA), bisphenol-A (BPA) and methacrylic acid
. Rising demand for MMA in LCD's and the electronic industry is likely to subsequently boost acetone demand over the next six years.
The company, with around 300 employees on Teesside, manufactures a total of around 250,000 tonnes a year of two "building block" products used in the manufacture of acrylics - methyl methacrylate (MMA) and methacrylic acid
(MAA) at its 69-acre Cassel Site at Billingham, Lucite's largest global production site for MMA manufacture.
L-Phenylalanine, methacrylic acid
(MAA), ethylene glycol dimethacrylate (EGDMA), trichloroacetic acid (TCA), trifluoroacetic acid (TFA), acetonitrile, toluene, tetrahydrofuran (THF), dimethyl sulfoxide (DMSO), chloroform, ortho phenyl aldehyde (OPA), N-methyl-L-phenylalanine, potassium phosphate monobasic (KH2PO4), pancreatin and methanol were purchased from Sigma-Aldrich (Steinheim, Germany).
The vinyl monomers used were acryloyl diphosphoric acid (ADPA), acrylic acid (AA), sodium styrenesulfonate (NaSS), and methacrylic acid
The USP (2008) describes polymethacrylates, copolymers of methacrylic acid
, as cation and anion synthetic polymers of dimethylaminoetylmethacrylates, methacrylic acid
and methacrylic acid
esters in several proportions.
Studies have found that the ionic contact lenses (in particular those which contain methacrylic acid
, for example 1day Acuvue) tend to attract more protein deposits than the non-ionic lenses.
Additionally, there is much interest in Eudragit L-100 (a copolymer of methacrylic acid
and methylmethacrylate) which was utilized as a reversibly soluble and insoluble immobilization matrix for immobilization of the widely used technological enzymes such as xylanase (Sardar et al., 2000; Gaur et al., 2005), cellulase (Zhang et al., 2010), and amylase (Cong et al., 1995), as well as a pH-dependent enteric coating polymer for the efficacious colon-specific drug delivery system (Venkatesh et al., 2009).
