Polyethylene glycol methacrylate PEGMA

Graft copolymers were prepared by both classical strategies, that is, from enzymatically obtained macromonomers by subsequent chemical polymerization and by enzymatic grafting from hydroxyl functional polymers. Kalra et al. studied the synthesis of PPDL graft copolymers from macromonomers, which were obtained by the enzymatic ROP of pentadecalactone (PDL) from hydroxyethyl methacrylate (HEMA) and polyethylene glycol) methacrylate (PEGMA) [40]. Subsequently graft copolymers were obtained by free radical polymerization of the macromonomers. A similar approach was published by Srivastava for the HEMA-initiated enzymatic ROP of CL and subsequent free radical polymerization [41]. 

The most widely investigated temperature-responsive biomedical polymer is poly(A-isopropyl acrylamide) (pNIPAM). This polymer is the focus of Chapter 1 in this book, and therefore it will not be discussed in depth here. However, pNIPAM has been paired with polyampholyte copolymers and applied to nanoparticle separations (Das et al., 2008), drug delivery (Bradley, Liu, Keddie, Vincent, Burnett, 2009 Bradley, Vincent, Burnett, 2009), and tissue engineering applications (Xu et al., 2008). In a related system, latridi et al. (2011) also used the LCST-responsive properties of polyethylene glycol methacrylate (PEGMA) copolymerized with methac-rylic acid and 2-(diethylamino) ethyl methacrylate in a temperature- and pH-sensitive doxorubicin drug delivery system. However, the primary focus of this study was to demonstrate the pH-dependent release properties as discussed earlier. 

Polymer electrolytes in EC-devices reported between 1998 and 2001 (Granqvist, 2003) were e.g., polyethylene oxide (PEO) and (PAMPS) as H+ conducting polymers and Li+ conducting polymers were based e.g., on polymethyl-methaaylate (PMMA) copolymerized with propylene carbonate or poly(ethylene glycol methacrylate) (PEGMA) copolymerized with PEO or poly(vinyhdene fluoride) (PVDF) to which was added an appropriate Li salt to turn them conducting. 

Finally, SIP of polyethylene glycol methyl ether methacrylate (PEGMA) was carried out, and PS/Poly(PEGMA) segregated binary brashes were prepared. SIP ATRP of PEGMA was carried out with maximum precaution to avoid oxygen. For this purpose, CuBr (80.3 mg, 0.56 mmol), CuBr2 (50 mg,...
