Glycerol monomethacrylate

If ATRP is conducted in methanol, under the same conditions, the rate of polymerisation is slower (95% conversion required 2-5 h at 20 °C). However, for several hydrophilic monomers such as 2-hydroxyethyl methacrylate [HEMA] and glycerol monomethacrylate [GMA], methanolic ATRP is the preferred method for optimal living character since narrower polydispersities (typically 1.10 to 1.20) and better blocking efficiencies are generally obtained. 

We have recently evaluated the ATRP of a wide range of hydrophilic monomers such as 2-sulfatoethyl methacrylate (SEM), sodium 4-vinylbenzoate (NaVBA), sodium methacrylate (NaMAA), 2-(dimethylamino)ethyl methacrylate (DMA), 2-(iV-morpholino)ethyl methacrylate (MEMA), 2-(diethylamino)ethyl methacrylate (DEA), oligo(ethylene glycol) methacrylate (OEGMA), 2-hydroxyethyl methacrylate (HEMA), glycerol monomethacrylate (GMA), 2-methacryl-oyloxyethyl phosphorylcholine (MPC), and a carboxybetaine-based methacrylate [CBMA]. Their chemical structures and literature references (which contain appropriate experimental details) are summarised in Table 1.

In contrast to nanofibrillar gels made of biopolymers that disassemble upon heating, nanofibrillar gels made of wormlike micelles exhibit a unique thermore-sponsive behavior [10, 44]. As described above in Sect. 3.2, cooling of the gel formed by wormlike micelles of poly(glycerol monomethacrylate)-b/< c -poly (2-hydroxypropyl methacrylate) yielded small spherical micelles [10]. Transformation of the nanofibrUs into spherical micelles led to disassembly of the transient network. Consequently, at a low temperature of 4 °C, the system exhibited a Uquid-like behavior with G" > G, whereas at 25 °C the system had a soUd-like behavior with G > G".
