MMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications.
Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH 2 =C(CH 3)CO 2 H. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor.
The monomer is a viscous liquid with a pungent odour. The first polymeric form of methacrylic acid was described in 1880 by Engelhorn and Fittig. The use of high purity monomers is required for proper polymerization conditions and therefore it is necessary to remove any inhibitors by extraction (phenolic inhibitors) or via distillation. [ 2 ]
These properties are mainly referred to a tightly bound hydration layer around each zwitterionic group, which effectively suppresses protein adsorption and thus, improves anti-fouling behavior. [ 3 ] [ 4 ] Therefore, polysulfobetaines have been typically employed as ultrafiltration membranes, [ 4 ] blood-contacting devices, [ 5 ] and drug ...
The preparation of such nanogels via the in situ polymerization method begins with free proteins dispersed in an aqueous solution along with cross-linkers and monomers, followed by addition of radical initiators, which leads to the polymerization of a nanogel polymer shell that encloses a protein core. Additional modification of the polymeric ...
Some celebs, however, did not stick to dogs, cats, rabbits, and fish. They chose companions that were far more exotic, and in some cases, completely unsuitable as pets.

Protein therapeutics are proteins used as experimental or approved therapies for disease states. They include "monoclonal antibodies (mAbs), peptide hormones, growth factors, plasma proteins, enzymes, and hemolytic factors" [1] While proteins can be more specific and flexible in their mechanism of action compared to small-molecule drugs, duration of action and drug delivery can be a challenge.
