Acrylic acid Chemical-defined

Linear polystyrene can be functionalized by various methods . The functional group capacity in these polymers diould not be too high otherwise, steric complications may arise. Poly(ethylene ycol) has been found to be most suitable for liquid-phase synthesis. This linear polyether and the block copolymers with functional groups at defined distances are chemically stable and soluble in a large number of solvents including water and can be precipitated selectively. Partially hydrolyzed poly(vinylpyrrolidone) and its copolymers with vinyl acetate were successfully applied in peptide synthesis. Poly(acrylic acid), poly(vinyl alcdiol), and poly-(ethylenimine) are less suitable for the sequential type synthesis because of the... 

Acrylics are defined as the family of materials having a similar chemical structure but a wide range of properties. They result from the polymerisation of esters and other derivatives of acrylic acid and methacrylic acid. 

Scheme 30.13 Synthesis of well-defined three-miktoarm star polymers using a combination of ATRP and CuAAC click" coupling. Amphiphilic star polymers were prepared that contain one hydrophobic arm and two hydrophilic poly(acrylic acid) arms. Reproduced with permission from Ref. [108] 2006, American Chemical Society.

With the development of DESs, they have been applied on some polymerization reactions that are carried out at relatively high temperatures. In these synthetic processes, the eutectic mixtures can act as true solvent-template reactant systems, and thus the DES is at the same time the precursor, the template, and the reactant medium for the fabrication of the desired polymeric material with a defined morphology or chemical composition. Monte and co-workers have reported i) the frontal polymerizations carried out in the eutectic mixtures ChCl/Acrylic acid and ChCl/Mac, " ii) the synthesis of poly(octane-diol-co-citrate) elastomers using eutectic mixtures of 1,8-octanediol and lidocaine at temperatures below 100 C (see Figure 20.3.4), " and iii) the synthesis of poly(acrylic acid)-carbon nanotube composites in the eutectic mixture ChCl/Aciylic acid.
