2-hydroxyl ethyl methacrylate HEMA

UF membranes were plasma-grafted with hydrophilic monomers to increase their surface hydrophilicity and hence improve the filtration of the protein. Ulbricht and Belfort (1995) used He or He/water plasma to graft AAc, methacrylic acid, and 2-hydroxyl-ethyl methacrylate (HEMA) onto polyacrylamide and PSU UF membranes. A PVDF nanoflber membrane graft copolymerized with methacrylic acid seemed to retain a high flux performance while its pore size was significantly smaller (Kaur et al. 2007). 

Proton-conducting GPE suitable for ECD applications were prepared by the co-polymerisation AMPS and ethylene glycol methacrylate phosphate (EGMP) either with MMA, GMA or 2-hydroxyl ethyl methacrylate (HEMA) in polar aprotic solvents, such as PC, EC or DMF. Use of the copolymers instead of polyAMPSA allowed the preparation electrolytes with various polymer matrix contents and various concentration of AMPS or EGMP. Gels swollen with solvent mixtures containing more than 40 wt% PC were completely amorphous. This property is important for the electro-chromic applications serious crystallization problems which severely decrease ionic conductivity are avoided. 

Multifunctional initiators, produced by dendrimer techniques, have been used to synthesize dendrimer-like star-block copolymers by ATRP method (Hedrick et al., 1998). Starting from a hexafunctional initiator, e-caprolactone was polymerized and each hydroxyl group was then chemically transformed into two 2-bromo-isobutyrate moieties, which were used to initiate the ATRP of either MMA or a mixture of MMA and hydroxy ethyl methacrylate (HEMA) to produce, in the latter case, dendrimer-hke star-block copolymer composed of a poly(e-caprolactone) core... 

Typically, an automotive quality acrylic will be formulated with a mixture of monomers selected fixim styrene (S), methyl methacrylate (MMA), butyl methacrylate (BMA) and butyl acrylate (BA). The hydroxy functionality is introduced via a monomer such as hydroxy ethyl acrylate (HEA) or hydroxy ethyl methacrylate (HEMA) to give hydroxyl values of between 50 and 120 mgKOH/g of solid resin. In addition, a small quantity...
